ROMAND DE MATHEMATIQUES
Alex Furman. "Measurable group theory". Abstract: In the course I will give a survey of results involving infinite discrete groups and topics involving: Ergodic theory, super-rigidity phenomena, rigidity vs. deformation techniques, and actions on manifolds.
Anders Karlsson. "Interrelations between a few ergodic theorems." Abstract: I will explain the relationship of the noncommutative ergodic theorem in Ledrappier's first lecture with various previous ergodic theoretic results. Theorems of von Neumann, Birkhoff, Oseledec, Beck-Schwartz, Pazy, Kaimanovich, Marcinkiewicz-Zygmund, Aaronson, and Karlsson-Margulis will be mentioned. I will probably also state a few open questions.
Volodymyr Nekrashevych. "Self-similar families of groups". Abstract: We will talk about different self-similar families of groups acting on rooted trees, which appear in group theory and dynamics. In particular, we will talk about the family related to the quadratic polynomial z^2+i and show its remarkable properties, like density of isomorphism classes and existence of groups of non-uniform exponential growth.
