Professeur Yves BENOIST (Orsay)
"Discrete subgroups of SL(3,R)"
Résumé
Discrete subgroups of SL(2,R) were first studied in the nineteenth century by Fuchs, Klein, Schottky and Poincaré. They form nowadays a classical topic which has deep interactions with number theory, differential geometry, complex analysis, dynamical systems and probability theory.
In this course, we will focus on discrete subgroups of SL(3,R) and we will see that they have also nice interactions with the same five topics. This course will be composed of five independent lectures, each one emphasizing one of these interactions.
