% \begin{abstract}
% This package provides a \LaTeXe\ document class named |ua-thesis|
% for typesetting theses and dissertations in the official format required
% by the University of Arizona.  
% Moreover, there is a fully compatible alternative document class
% |my-thesis| for private copies of the dissertation, and the respective
% title pages are available as separate packages to work with ``any''
% document class.  
% \end{abstract}
% 
%
% \section{User Documentation}
%
% \subsection{Introduction}
%
% The |ua-thesis| document class is designed to conform with the official
% requirements of the Graduate College of the University of Arizona.  It is
% based on the |report| class which comes with the standard \LaTeX\
% distribution, and all commands are upward compatible with |report|
% and to a large extend with the |amsbook| class.  In other words, any
% document which works error free in those two classes should run with
% |ua-thesis|, too.  To automatically typeset all the required information,
% a few new commands are defined, which are explained below.
%
%
% \subsection{Classes and Options}
%
% The following classes and packages are provided:
%
% \begin{description}
%
% \item[\texttt{ua-thesis}]
% The official University of Arizona thesis document class.  The |draft|
% option is a paper saver---the automatic generation of front matter pages
% other than the title page will be suppressed, and single spaced printing
% will be used throughout the document.  The |final| option activates
% ``double spaced'' layout at the required places and creates the full set
% of front matter pages.  The default is |draft|. 
%
% Note that the draft option is passed through to the underlying |report|
% class, i.e.\ thick black rules will indicate the location of overfull
% |hbox|es.
%
% The |ua-thesis| class automatically loads the |amsmath|, |amssymb| and
% |amsthm| packages which considerably improve the mathematical
% typesetting capabilities of \LaTeX.  The use of these macros is strongly
% recommended. 
%
% The default type-size in this document class is 12pt and should not be
% changed.  Subsubsections 
% produce unnumbered run-in headings which do not appear in the Table of
% Contents, therefore their use is discouraged.
%
% \item[\texttt{my-thesis}]
% An alternative to |ua-thesis| to produce private copies of your
% dissertation which don't look so reminiscent of the typewriter age.  It
% is based on the |pcms-l| document class by the American Mathematical
% Society, which was designed to typeset monographs for the Park City/IAS
% Mathematics Series.  It is similar to |amsbook|, but has a less crowded
% look.
%
% \item[\texttt{ua-title}]
% The official University of Arizona title page as a separate package.
% Useful if you want to build your own private thesis class, but want to
% use the official title page.  It redefines the |\maketitle| command and
% also provides (potentially useless) definitions for all the commands
% described in the next section.
%
% The package is neither guaranteed nor tested to work with any specific
% document class.  You have to try and see.
%
% \item[\texttt{my-title}]
% The equivalent to |ua-title|, but with the title page of the |my-thesis|
% class. 
% 
% \end{description}
% So, the first line in your dissertation file should be
% \begin{verbatim}
%   \documentclass{ua-thesis}
% \end{verbatim}
% or, for the final printout,
% \begin{verbatim}
%   \documentclass[final]{ua-thesis}
% \end{verbatim}
% If you change the document class from |ua-thesis| to |my-thesis| or vice
% versa, the 
% first \LaTeX\ run might produce error messages because the format of the
% auxiliary files (|.aux|, |.toc| etc.) is incompatible between the two.
% Type |s| or |q| to ignore all error messages and run \LaTeX\ a second
% time, or manually delete all auxiliary  
% files before changing the document class.
% 
%
% \subsection{Commands for Specifying the Front Matter}
%
% As in the standard document classes, the title of your thesis is
% specified by
% \begin{verbatim}
%   \title{This is the Title of my Dissertation \\
%          and This is the Second Line}
% \end{verbatim}
% where line breaks can be forced with |\\| if the automatic line
% breaking does not give a satisfactory result.  But remember, the Graduate
% College imposes a maximum of three lines in the title---\LaTeX\ does not
% check this for you.  An optional argument can be given for reasons of
% compatibility with the AMS classes, but will be ignored.
%
% Your name is specified with
% \begin{verbatim}
%   \author{Firstname Lastname}
% \end{verbatim}
% again, an optional argument will be ignored.  Use
% \begin{verbatim}
%   \date{1996}
% \end{verbatim}
% set the year of your graduation.  If you omit this command, the current
% day, month and year will be printed, which may be useful for keeping
% track of different draft versions.
% The only other command that is required for the final version of every
% dissertation is 
% \begin{verbatim}
%   \director{Firstname Lastname}
% \end{verbatim}
% to specify the name of your dissertation advisor.  It will appear on the
% Special Abstract which is automatically generated.  
%
% Now the optional commands. The name of your department is set with
% \begin{verbatim}
%   \department{Department of Metaphysics}
% \end{verbatim}
% The default is ``Graduate Interdisciplinary Program in Applied
% Mathematics''. If you are in the ``Department of Metaphysics'', you have
% to use this command.
%
% If you are writing a Masters thesis, you have to explicitly specify the
% name of your degree.  Use
% \begin{verbatim}
%   \degree{Masters of Arts}
% \end{verbatim}
% The default is ``Doctor of Philosophy''.  The abbreviation of the
% degree is needed for the Special Abstract and can be with
% \begin{verbatim}
%   \degreeabbrev{M.A.}
% \end{verbatim}
% The default is ``Ph.D.''.  Moreover, for Masters theses, the Copyright
% Page will have an additional part for the approval signature of your
% advisor.  It will be automatically generated whenever you specify your
% advisor's title with
% \begin{verbatim}
%   \directortitle{Professor of Mathematics}
% \end{verbatim}
% The default is empty and \emph{must not be changed for doctoral
% dissertations}. 
%
% If you have to specify a major department
% different from the department above, use
% \begin{verbatim}
%   \major{Agriculture}
% \end{verbatim}
% The default is empty.  
%
% You can copyright your dissertation or thesis by writing
% \begin{verbatim}
%   \copyrightholder{Firstname Lastname Year}
% \end{verbatim}
% The default is empty.  If you use this command, the 
% Copyright Page will automatically change to the required
% legalese for copyrighted dissertations or theses.
% 
%
% \subsection{Examples for the Root File}
%
% For long documents such as theses, it is useful to split the \LaTeX\
% source code into several files.  The root file is the file that you run
% \LaTeX\ on.  Subordinate files are included with |\include|.
%
% \subsubsection{A Doctoral Dissertation}
%
% The example below also shows how to load the |graphics| package, which in
% particular supports the inclusion of postscript images.  Note that you
% can specify the |draft| or |final| option for the graphics package
% separate from the global options of the document class.
%
% The |ua-thesis| class is designed to create a |.dvi| file that strictly
% adheres to the required page margins.   The printer hardware or the
% driver implementation, however, may have tolerances that cause the image
% to shift on the page.  This can be corrected by using |\hoffset|
% and |\voffset|.  The example below works well with the current printers
% in the Math Department.
%
% You don't need to use |\chapter*{Dedication}| for the Dedication if you
% don't like the heading.  You can simply start a new page with |\newpage|,
% but then you are completely responsible for the formatting of that page,
% including the switch to double-spaced printing as is officially required
% (this can be done, for example, by using |\doublespaced|).
%
% \begin{verbatim}
% \documentclass[draft]{ua-thesis}
% \usepackage[final]{graphics}
%
% \hoffset -2.1mm
%
% \director{Advisor's Name}
% \date{1996}

% \subsection{The Files and Further Documentation}
%
% Currently, the sources and all documentation are contained in the
% following three files.
% \begin{description}
%
% \item[\texttt{ua-classes.dtx}]
% User guide and documented source code.  The document you are reading has
% been obtained by running |latex ua-classes.dtx|. 
%
% \item[\texttt{ua-classes.ins}]
% The installation file. Running |latex ua-classes.ins| will 
% generate the class  files |ua-thesis.cls| and  |my-thesis.cls| as well
% as the title page packages
% |ua-title.sty| and |my-title.sty| from the universal source file
% |ua-classes.dtx|.
%
% \item[\texttt{ua-example.tex}]
% An example dissertation generated from the official Manual for Theses and
% Dissertations by the Graduate College.  The file has been obtained via
% the web and manually converted into \LaTeX.  It both serves as an example
% and contains the official formating instructions as of May 1996.  Be sure
% to check for changes before you submit your dissertation. 
%
% \end{description}
%
%
% \subsection{Bugs and Changes}
%
% All changes and bug fixes must be done in the file |ua-classes.dtx|,
% and \emph{not} in the files generated by the docstrip utility.  Moreover,
% they must be clearly annotated with a date, name and comments explaining
% each change.
%
%
% \section{The Code}
%
% This section contains a commented listing of the source code.
% It is intended for \TeX perts to facilitate alterations and
% debugging (hopefully the latter will not become necessary).
% 
% \subsection{The Identification Part}
%
%    \begin{macrocode}
\NeedsTeXFormat{LaTeX2e}
%&lt;*ua-thesis&gt;
\ProvidesClass{ua-thesis}
              [1997/03/08 UA Thesis Class]
%&lt;/ua-thesis&gt;
%&lt;*my-thesis&gt;              
\ProvidesClass{my-thesis}
              [1997/03/08 My Private Thesis Class]
%&lt;/my-thesis&gt;
%&lt;*ua-title&gt;
\ProvidesPackage{ua-title}[1997/03/08]
%&lt;/ua-title&gt;
%&lt;*my-title&gt;
\ProvidesPackage{my-title}[1997/03/08]
%&lt;/my-title&gt;
%    \end{macrocode}
%
% \subsection{Package Options}
%
% We pass the global package options through to the underlying
% document class.  In the |ua-thesis| class we also keep track of
% whether the |draft| or |final| option is switched on because
% we will link certain document features (see Section 1) to
% this option.
%    \begin{macrocode}
%&lt;*ua-thesis&gt;
\newif\iffinal@
\DeclareOption{final}{%
  \final@true
  \PassOptionsToClass{final}{report}}
\DeclareOption{draft}{%
  \final@false
  \PassOptionsToClass{draft}{report}}
\ExecuteOptions{draft}  
\DeclareOption*{\PassOptionsToClass{\CurrentOption}{report}}
\ProcessOptions
%&lt;/ua-thesis&gt;
%    \end{macrocode}
% In the |my-thesis| class, nothing particular happens.
%    \begin{macrocode}
%&lt;*my-thesis&gt;
\DeclareOption*{\PassOptionsToClass{\CurrentOption}{amsbook}}
\ProcessOptions
%&lt;/my-thesis&gt;
%    \end{macrocode}
%
% \subsection{The Underlying Document Classes}
%
% The official |ua-thesis| class is based on the standard |report|
% document class.  We load it with the |12pt| option as default,
% which is smallest size allowed.  We have to load the 
% packages of the AMS math bundle explicitly.
% Added 1997/3/8: In fact, even |ua-thesis| breaks with old versions
% of the AMS macros, so we add a release date to |\RequirePackage|.
%    \begin{macrocode}
%&lt;*ua-thesis&gt;
\LoadClass[12pt]{report}
\RequirePackage[reqno]{amsmath}[1996/10/24]
\RequirePackage{amsfonts}[1996/10/24]
\RequirePackage{amsthm}[1996/10/24]
\RequirePackage{ua-title}
%&lt;/ua-thesis&gt;
%    \end{macrocode}
% We want the equation numbers on the right, thus the |reqno| option.
%
% The |my-thesis| class is based on the |amsbook| class
% with modifications adopted from the |pcms-l| package, also by the
% AMS.  The packages of the AMS math bundle are loaded by default from
% within |amsbook|.  Added 1996/12/05: The updated version works only
% with the new release of the AMS macros, dated 1996/10/24.
%    \begin{macrocode}
%&lt;*my-thesis&gt;
\LoadClass[reqno]{amsbook}[1996/10/24]
\RequirePackage{my-title}
%&lt;/my-thesis&gt;
%    \end{macrocode}
%
% \subsection{General Style Settings for \texttt{ua-thesis}}
%
% Redefine the name of the Table of Contents and the References
% according to the Graduate College regulations.
% We also have to redefine |\listfigurename| and |\listtablename| with
% |\def| (although the names are not changed),
% otherwise they have the wrong status with respect to the \TeX
% internals |\outer| and |\long|, and the |\ifx| statements in the
% |\@chapterstar| macro won't work.
%    \begin{macrocode}
%&lt;*ua-thesis&gt;
\def\contentsname{Table of Contents}
\def\bibname{References}
\def\dedicationname{Dedication}
\def\listfigurename{List of Figures}
\def\listtablename{List of Tables}
%    \end{macrocode}
% Set the page margins as required by the Graduate College: Top margin is
% $1.5$in, bottom margin is $1$in, left margin is $1.5$in and the right
% margin is $1$in.  We grant an extra $0.2$in to the bottom margin to allow
% for printer tolerances and to account for characters that extend below
% the base line (e.g.\ the character ``y'').
%    \begin{macrocode}
\topmargin      0in
\headheight     \baselineskip
\headsep        0.6in
\addtolength{\headsep}{-\headheight}
\footskip       0in
\textheight     \paperheight
\addtolength{\textheight}{-2.7in}
\oddsidemargin  0.5in
\evensidemargin 0.5in
\marginparwidth 0in
\marginparsep   0in
\textwidth      \paperwidth
\addtolength{\textwidth}{-2.5in}
%    \end{macrocode}
% Macros to switch from single-spaced to double-spaced printing.
% The command |\doublespaced| takes only effect when it is used
% with the |final| option.
%    \begin{macrocode}
\def\singlespaced{\baselineskip=\normalbaselineskip}
\def\doublespaced{\iffinal@ \baselineskip=1.5\normalbaselineskip \fi}
%    \end{macrocode}
% Finally, we define the page styles as required.  As we are modifying the
% |\topskip| when typesetting chapter headings and when selecting
% page style |continued|, we save the default value and restore
% it on ``normal'' pages.
%    \begin{macrocode}
\newlength{\@topskipsave}
\@topskipsave\topskip
%    \end{macrocode}
% The page style |topright| is used on normal pages.  It puts
% the page number into the top
% header at the right margin of each page.
%    \begin{macrocode}
\def\ps@topright{%
    \let\@mkboth\@gobbletwo
    \topskip\@topskipsave
    \def\@oddhead{\normalfont\hfil\thepage}
    \let\@evenhead\@oddhead
    \def\@evenfoot{}
    \def\@oddfoot{}}
%    \end{macrocode}
% Page style |continued| is for the second and following pages of
% the Table of Contents, the List of Figures and the List of Tables.
% The macro |\@continued| contains the required heading for those
% pages, e.g.\ ``Table of Contents---Continued''.
%    \begin{macrocode}
\def\ps@continued{%
    \let\@mkboth\@gobbletwo
    \topskip 0.5in
    \def\@oddhead{\raisebox{-0.5in}{\@continued}%
                  \hfil\normalfont\thepage}
    \let\@evenhead\@oddhead
    \def\@evenfoot{}
    \def\@oddfoot{}}
%    \end{macrocode}
% The \TeX\ mechanism for starting pages is rather mysterious.  There is
% some extra space associated with the variable |\topskip|. However, it
% is not sufficient to just set |\topskip| to zero.  One moreover has to
% place a box of zero height onto the page, otherwise \TeX\ inserts extra
% vertical space, and we lose precise control over the placements
% of the layout elements.  The following macro is called whenever a
% title page (main title, chapter title, etc.) is started.
%    \begin{macrocode}
\def\@notopskip{\topskip\z@ \hrule height\z@}
%&lt;/ua-thesis&gt;
%    \end{macrocode}
%
% \subsection{Some Style Defaults of the \texttt{my-thesis} Class}
%
% We mostly follow the defaults given by the |amsbook| class, but there
% are few things worth changing.  First we add some space between the items
% of a list---we don't have to be too stingy with vertical space.
% The next four lines are copied from |amsbook.cls| with changed definition
% for |\itemsep|.
%    \begin{macrocode}
%&lt;*my-thesis&gt;
\def\@listI{\leftmargin\leftmargini \parsep\z@skip
  \topsep\listisep \itemsep\topsep
  \listparindent\normalparindent}
\let\@listi\@listI
%    \end{macrocode}
% Moreover, sections are to be numbered within chapters, and we give the
% Abstract the appearance of an unnumbered chapter.
%    \begin{macrocode}
\numberwithin{section}{chapter}
\renewenvironment{abstract}%
  {\chapter*{Abstract}}{}
%    \end{macrocode}
% We must define a bibliography style to avoid an error message.
%    \begin{macrocode}  
\bibliographystyle{amsplain}
%&lt;/my-thesis&gt;
%    \end{macrocode}
%
% \subsection{The Title Page Packages}
%
% The title page macros are put into separate files, so that they can
% be used in conjunction with other document classes, if this is
% desirable.
%
% First some common code that defines the macros for
% various layout elements in the title page(s).  The |my-thesis| class
% will not use all of them, but their definition is required anyway to
% assure compatibility with |ua-thesis|. The defaults are set as follows:
%    \begin{macrocode}
%&lt;*ua-title|my-title&gt;
\let\@title\@empty
\let\@author\@empty
\let\@copyright\@empty
\def\@thesis{Dissertation}
\def\@department{Graduate Interdisciplinary Program \\
                 in Applied Mathematics}
\def\@degree{Doctor of Philosophy}
\def\@degreeabbrev{Ph.D.}
\let\@major\@empty
\let\@director\@empty
\let\@directortitle\@empty
%    \end{macrocode}
% In the following, changed |\newcommand| to |\renewcommand|
% because the new release
% of the AMS classes seems to define |\copyrightholder| while the
% old release doesn't (1996/12/05).
%    \begin{macrocode}
\def\copyrightholder#1{\gdef\@copyright{#1}}
\newcommand{\thesis}         [1]{\gdef\@thesis{#1}}
\newcommand{\department}     [1]{\gdef\@department{#1}}
\newcommand{\degree}         [1]{\gdef\@degree{#1}}
\newcommand{\degreeabbrev}   [1]{\gdef\@degreeabbrev{#1}}
\newcommand{\major}          [1]{\gdef\@major{#1}}
\newcommand{\director}       [1]{\gdef\@director{#1}}
\newcommand{\directortitle}  [1]{\gdef\@directortitle{#1}}
%    \end{macrocode}
% We redefine the |\title| and |\author| commands to follow the
% AMS syntax.  The optional
% argument allowed in the AMS classes is simply ignored without
% an error message.
%    \begin{macrocode}
\renewcommand{\title} [2][]{\gdef\@title{#2}}
\renewcommand{\author}[2][]{\gdef\@author{#2}}

% \subsubsection{Setting the Date with Spaces Between Digits}
% 
% In order to increase the inter-letter space in the date, we resort to
% a technique which is a simplified version of the 
% |letterspace| package (by Philip Taylor, described in The
% \LaTeX\ Companion).  The macro |\spaced| puts spaces between all the
% characters of its argument.  
%    \begin{macrocode}
%&lt;*ua-title|my-title&gt;
\def \spaced #1%
    {\edef \3{#1}%
     {\expandafter \insertsp@ces \3\@nd}%
    }
\def \insertsp@ces #1#2\@nd
    {\def \1{#1}%
     \def \2{#2}%
     \1%
     \ifx \1\empty \else \ifx \2\empty \else \space \fi \fi
     \ifx \2\empty
          \let \n@xt = \relax
     \else
          \futurelet \2\m@kespaceexplicit #2\@nd

% \subsubsection{Abstract and Special Abstract}
%
% Setting the abstract in the official thesis class
% is tricky.  Since we have to typeset it twice, for
% the regular and the special abstract, and we want to keep the regular
% \LaTeX\ syntax of having an |abstract| environment, we somehow have to 
% save the body of the abstract environment for further processing.
% This is quite difficult to do in \TeX, but fortunately the |amsmath|
% package has solved this problem for us.  It defines the internal macro
% |\collect@body| which takes a single argument, namely the name of
% a macro which does the processing.  This macro is then called by
% |\collect@body|, and given the contents of the environment body as
% its argument.  We redefine these macros here, mainly for the reason that
% we want the auxiliary macros |\collect@@body|
% and |\Addto@envbody| to be defined with
% |\long\def|, so that the abstract can have more than one paragraph.
% We capitalize all macros not to interfere with the |amsmath| package
% (actually, our change would only change |amsmath|s response to
% errors, not its behavior with correct code).
%    \begin{macrocode}
\long\def\Addto@envbody#1{\@envbody\@xp{\the\@envbody#1}}
\def\Collect@body#1{%
    \@envbody{}%
    \def\process@envbody{%
        \@xp#1\@xp{\the\@envbody}%
    }%
    \@xp\let\csname\@currenvir\endcsname\Collect@@body
    \csname\@currenvir\endcsname
}
\long\def\Collect@@body#1\end#2{%
    \def\@tempa{#2}%
    \ifx\@tempa\@currenvir
        \Addto@envbody{#1}%
        \@xp\edef\csname\@currenvir\endcsname{%
            \@nx\process@envbody\@nx\end{\@tempa}%
            }%
    \else
        \Addto@envbody{#1\end{#2}}%
    \fi
    \csname\@currenvir\endcsname
}
%    \end{macrocode}
% The details of the above are explained in |amsmath.dtx|. For us it
% is mainly a convenience, and the remainder of the abstract
% macro can be coded in a very elegant way.
%    \begin{macrocode}
\renewenvironment{abstract}{%
  \Collect@body\@SetAbstract}{}
%    \end{macrocode}
% Now the macro |\@SetAbstract|, which actually does the work. First
% we typeset the regular abstract.
%    \begin{macrocode}
\long\def\@SetAbstract#1{%
  \chapter*{Abstract} 
  #1
  \clearpage
%    \end{macrocode}
% Then the special abstract. We typeset it only in the final version. Note
% that we have to save the page counter at the beginning of the special
% abstract, so that it doesn't interfere with the page numbering of the
% main document.

% For numbered chapters we do all the usual things:  Set the page style in

% create the Table of Contents entry and add extra space into the
% List of Figures and List of Tables.
%    \begin{macrocode}
\def\@chapter[#1]#2{%
  \pagestyle{topright}
  \refstepcounter{chapter}%
  \typeout{\@chapapp \space \thechapter}
  \addcontentsline{toc}{chapter}%

  \addtocontents{lof}{\protect\addvspace{\medskipamount}}
  \addtocontents{lot}{\protect\addvspace{\medskipamount}}
%    \end{macrocode}

%    \end{macrocode}
% Unnumbered chapters are more tricky.  Several explicitly format decisions
% have to be made to typeset all the special ``chapters'' in the
% front matter of the dissertation according to the official requirements.
%
% The following rules are implemented: The Dedication is typeset
% double-spaced.  The Table of Contents, List of Figures and List of Tables
% must be get pagestyle |continued| and be single-spaced.  In all other
% cases pagestyle |topright| is selected.
% Only those unnumbered chapters that
% come after the Table of Contents will get an entry in the Table of
% Contents.  An arbitrary unnumbered chapter that comes after the
% Table of Contents will be double-spaced, the exception is the References,
% which are single-spaced.   If an unnumbered chapter comes before the
% Table of Contents, no explicit decision between single and double-spaced
% is made.  The effect is that the Acknowledgments will be single-spaced,
% provided they are placed in the officially required order.
%    \begin{macrocode}
\def\@chapterstar#1{%
  \typeout{#1}

%

% multiple authors.
%    \begin{macrocode}
%&lt;*my-thesis&gt;
\def\chapter{\cleardoublepage \pagestyle{headings}%

%    \end{macrocode}
% For typesetting the chapter head we fixed one problem with

% \subsection{The Table of Contents}
%
% Modifying the design of the Table of Contents is slightly tricky.  An
% additional complication on our case is that the |amsbook| class which is
% the base for |my-thesis| considerably modifies the internals of the
% contents mechanism.  Therefore the code for the two classes is quite
% different.
%
% \subsubsection{The Official Table of Contents}
%
% At the beginning of the Document we compute the width of the boldfaced
% number 999 which we take as the maximum width of a page number in the
% Table of Contents.  Note that we have to use |\AtBeginDocument| to avoid
% typesetting anything in the preamble of the document as this will
% potentially interfere with packages that modify fonts.
%    \begin{macrocode}
%&lt;*ua-thesis&gt;
\newlength{\@auxlength}
\AtBeginDocument{%
  \settowidth{\@auxlength}{\textbf{999}}
  \renewcommand{\@pnumwidth}{\@auxlength}}
%    \end{macrocode}
% We want all section numbers to end with a period, and modify the
% definition of |\numberline| accordingly.
%    \begin{macrocode}  
\def\numberline#1{\hb@xt@\@tempdima{#1.\hfil}}
%    \end{macrocode}
% The same for chapter entries; in case the chapter heading takes more than
% one line, we set |\hangindent| to indent the second and following lines.
%    \begin{macrocode}
\def\chapterline#1{%
  \advance\hangindent\@tempdima
  \hbox{#1.\space\space\hfil}}  
%    \end{macrocode}
% The macro |\l@chapter| is called to set the Table of Contents line for a
% chapter entry.  
%    \begin{macrocode}
\renewcommand*\l@chapter[2]{%
  \addpenalty{-\@highpenalty}%
  \vskip 1.0em \@plus\p@
  \begingroup
    \advance\hangindent 1.5em
    \@dottedtocline{0}{0pt}{0pt}{\scshape #1}{\bfseries #2}
  \endgroup
  \penalty\@highpenalty}
%    \end{macrocode}
% And the corresponding macros for figures and tables.
%    \begin{macrocode}
\renewcommand*\l@figure[2]{%
  \@dottedtocline{1}{0pt}{30pt}{\textsc{Figure} #1}{#2}}
\renewcommand*\l@table[2]{%
  \@dottedtocline{1}{0pt}{30pt}{\textsc{Table} #1}{#2}}
%&lt;/ua-thesis&gt;
%    \end{macrocode}
%
%
% \subsubsection{My Table of Contents}
%
% The |amsbook| class automatically calculates the width of the section
% numbers which go into the Table of Contents.  Therefore we must
% manually compute the amount of indentation for subsection entries and
% subsubsection headings.  This is done at the beginning of the document,
% after |amsbook| has read the number widths found in the previous
% \LaTeX\ run from the |.aux| file.
%    \begin{macrocode}
%&lt;*my-thesis&gt;
\newlength{\@subsectionindent}
\newlength{\@subsubsectionindent}
\AtBeginDocument{%
  \setlength{\@subsectionindent}{1pc}
  \addtolength{\@subsectionindent}{\csname r@tocindent1\endcsname}
  \setlength{\@subsubsectionindent}{\@subsectionindent}
  \addtolength{\@subsubsectionindent}{\csname r@tocindent2\endcsname}}
%    \end{macrocode}
% Now we modify some other style parameters.  We want subsections, but
% not subsubsections to into the Table of Contents.  If subsubsections
% should appear in the Table of Contents, the command
% |\setcounter{tocdepth}{4}| can be used in the preamble of the document.
% We also need to make some minor spacing modifications.
%    \begin{macrocode}
\setcounter{tocdepth}{3}
\renewcommand{\@pnumwidth}{2em}
\def\numberline#1{\hbox{#1\quad}}
%    \end{macrocode}
% Finally we change |\l@chapter| to get a boldface font for chapter
% entries, and redefine the subsection macros to use the indentation
% calculated above. 
%    \begin{macrocode}
\renewcommand*{\l@chapter}[2]{%
  \@tocline{0}{10pt plus4pt}{0pt}{1pc}{\bfseries}{#1}{\bfseries #2}}
\def\l@subsection{\@tocline{2}{0pt}{\@subsectionindent}{}{}}
\def\l@subsubsection{\@tocline{3}{0pt}{\@subsubsectionindent}{}{}}
%    \end{macrocode}
% We don't want a List of Figures or a List of Tables.
%    \begin{macrocode}
\let\listoffigures\relax
\let\listoftables\relax
%&lt;/my-thesis&gt;
%    \end{macrocode}

% \Finale
