## Mathematics

This section contains my mathematical articles and notes, and a few from other mathematicians.

In 2003 I added the classical paper *Numbers of solutions of equations in finite fields* of *André WEIL* (with permission of the *American Mathematical Society*) that had at that time been unavailable.

In 2005 I worked with *Jean GIRAUD* to transcribe his class notes on *Riemann Surfaces* into TeX. In 2007 I transcribed the course of *Jean-Louis VERDIER* on the *fundamental group* into TeX.

In 2010 I republished the course on *plane curves of second order and their invariants* by *Ernst FREUDENTHAL* and *Werner HEINRICH*, supplemented in 2011 by the solutions booklet to their exercises. Also in 2011 I added the Bourbaki talk of *Enrico BOMBIERI* on *Counting points on curves over finite fields*.

In 2014 appeared my reedition of the SGA d’Orsay, « en hommage à *Michel DEMAZURE, Jean GIRAUD, Michel RAYNAUD et Jean-Louis VERDIER* » Séminaire de Géométrie Algébrique. In 2015 I provided a TeX edition of the booklet on kählerian varieties by *André WEIL*.

This section is organized into these subareas:

- mathematical recreation
- astronomy & physics
- algebra
- topology
- differential geometry
- algebraic geometry
- arithmetic
- representations

#### Timelines of mathematicians (and some physicists and astronomers)
