+%  Basic layout :

+\stdskip=6.6pt plus3.3pt minus3.3pt    
+%

+\setlength{\labelsep}{0.75em} 
+\newcommand{\stdspace}{\hskip 0.75em plus 0.15em \ignorespaces}
+\let\qua\stdspace  %  useful abbreviation 
+%
+%  Some style commands (\ppar is for principal paragraph breaks, \sh is
+%  for subheadings and \rk for remarks etc -- see also theorem style 
+%  below ) :
+%
+\newcommand{\ppar}{\par\goodbreak\vskip 8pt plus 3pt minus 3pt} 
+\newcommand{\sh}[1]{\penalty-800\ppar{\bf #1}\par\medskip\nobreak}
+\newcommand{\rk}[1]{\ppar{\bf #1}\stdspace}    
+%
+%
+%   Theorem style.  There are two recommended styles :
+%
+%   plain : for theorems, corollaries etc with heading bold
+%   and left justified, optional note bracketed in roman type
+%   and statement in slanted type.
+%
+%   definition : (alias remark)  for definitions, remarks etc with
+%   heading bold and left justified, optional note unbracketed in 
+%   slanted type and statement in roman type.
+%   
+%
+%  Redefine the amsthm styles plain, definition and remark to GT style:
+%
+\newtheoremstyle{plain}{14pt plus6.3pt minus6.3pt}{7.4pt plus3pt minus3pt}%
+{\sl}{}{\bf}{}{0.75em}{\thmname{#1}\thmnumber{ #2}\thmnote{\rm\stdspace(#3)}}
+%
+\newtheoremstyle{definition}{14pt plus6.3pt minus6.3pt}{7.4pt plus3pt minus3pt}%
+{\rm}{}{\bf}{}{0.75em}{\thmname{#1}\thmnumber{ #2}\thmnote{\sl\stdspace#3}}
+%
+\newtheoremstyle{remark}{14pt plus6.3pt minus6.3pt}{7.4pt plus3pt minus3pt}%
+{\rm}{}{\bf}{}{0.75em}{\thmname{#1}\thmnumber{ #2}\thmnote{\sl\stdspace#3}}
+%
+%  Default theorem style :
+\theoremstyle{plain}               
+%
+% Adapt the amsthm proof environment to GT style :
+%
+\renewenvironment{proof}[1][\proofname]{\par
+  \normalfont
+  \topsep\stdskip \trivlist
+  \item[\hskip\labelsep\bf
+    #1]\ignorespaces
+}{%
+  \qed\endtrivlist\par
+}
+%                 Knuth's \square macro :
+%
+\def\sqr#1#2{{\vcenter{\vbox{\hrule  height.#2pt
+	\hbox{\vrule width.#2pt height#1pt \kern#1pt \vrule width.#2pt}
+	\hrule height.#2pt}}}}
+%
+\def\sq{\sqr55}           %    A small square for end-of-proofs. 
+\def\qedsymbol{$\sqr55$}  %   (Define other size squares by varing the
+%                         %   the two numbers.)
+%
+%  Some useful abbreviations :
+%
+\newcommand{\co}{\colon\thinspace}    %  Colon with correct spacing for maps.
+\newcommand{\np}{\newpage}            %  Forced page break (new page).
+\newcommand{\nl}{\hfil\break}         %  New line.
+\newcommand{\cl}{\centerline}         %  Centerline
+\def\gt{{\mathsurround=0pt\it $\cal G\mskip-2mu$eometry \&\

+\let\@footnote@\footnote
+\def\footnote#1{\@footnote@{\small #1}}
+\let\fnote\footnote    % useful abbreviation for \footnote

+  \sbox\@tempboxa{##1##2}%

+%  Set displayskips to correct values :
+%
+\let\@document@\document
+\def\document{\@document@%
+\setlength{\abovedisplayskip}{\stdskip}
+\setlength{\belowdisplayskip}{\stdskip}}  
+%
+%
+%  Get the biblio style correct (10pt with small gaps):
+%
+\let\@thebibliography@\thebibliography
+\def\thebibliography#1 {\@thebibliography@{999}\small\parskip0pt % 
+plus2pt\relax}
+%
+%
