Teaching
A short text on the geometry of the triangle, or how complexes evacuate complexity and encourage us to move on.
The volume I of a book on general algebra-geometry , currently being finalized for the L3-M1 level, without much claim to originality except for a little effort on the algorithmic side of proofs (with the collaboration of Thomas Mordant, Laurent Moonens and Damien Simon).
A few slides to complement the Geometry course
for the "agrégation" (national competitive recruitment exam of high school teacher).
