Cours
Algèbre linéaire
L'objectif du cours est d'introduire les notions de base de l'algèbre linéaire et ses applications. 
Topologie
On commencera par rappeler le cadre purement axiomatique de la topologie, en particulier les produits d'espaces. Nous étudierons ensuite des notions de séparabilité et connexité, globale et locale. Enfin nous aborderons des constructions d'espaces topol...
Topologie algébrique
Nous étudions en profondeur la notion d'homologie d'un espace topologique, en mettant un poids important sur les méthodes de calcul, tout en assurant une assise théorique conséquente.
Working group in Topology I
The theme of the working group varies from year to year. Examples of recent topics studied include: Galois theory of ring spectra, duality in algebra and topology, and topological algebraic geometry.
Working group in Topology II
The theme of the working group varies from year to year. Examples of recent topics studied include: Galois theory of ring spectra, duality in algebra and topology, topological algebraic geometry and twisted K-theory.
