spacing
I've defined a custom section title as follows:
\renewcommand\thesection{Lecture \arabic{section} --}
This leaves an unwanted gap between "Lecture n -" and the title of the lecture.
For example, \section{Linear combinations and subspaces} gives the following output:
I would like there to be a normal text space between the numbering and title. How can I achieve this?
This is above all due to the bad syntax in:
\titleformat{\section}[block]{\Large\normalfont\bfseries}{#1}{.5em}{}
You've put #1 at the place reserved for formatting the label. A correct syntax would be, e.g.:
\titleformat{\section}[block]{\Large\normalfont\bfseries}{\arabic{section}.}{.5em}{#1}
Important are only the two lines maked with %%%%%%%%%%%%%%%%%%%

\title{\S 2. Sch\'emas et morphismes de sch\'emas}
\begin{document}

\section{Definition of Schemes}
\section{foo}
\end{document}
If you want only reduce the space after the title, then you need only a \vspace{- ...}:
\documentclass{smfart}
\usepackage{smfthm}
\title{\S 2. Sch\'emas et morphismes de sch\'emas}
\begin{document}
\maketitle
\vspace*{-1.5cm}
\section{Definition of Schemes}
\section{foo}
\end{document}
If the abstract should be directly after the tile use:
\makeatletter
\def\@maketitle{\cleardoublepage\thispagestyle{copyright}
\begingroup
\uppercasenonmath\shorttitle
\ifx\@empty\shortauthors \let\shortauthors\shorttitle

It's better to redefine the way a section counter is formatted (via
\@seccntformat) for this purpose than redefining the entire counter representation. Why? Redefining the counter representation would filter down to\labels as well, and therefore\references also.
