Workshop on Algebraic, Geometric and Probabilistic Aspects of Amenability
June 18 - July 13, 2007

Schedule of lectures for Week 4 (July 9 - July 13)

• Monday, July 9, 2007
  11:00 - 11:50: Volodymir Nekrashevych (Texas A&M): Contracting self-similar groups, I
  Abstract: Contracting self-similar groups appear naturally as iterated monodromy groups of expanding self-coverings of orbispaces. They include many examples of non-elementary amenable groups. An open question is if they all are amenable. We will discuss the relation of contracting groups to dynamical systems and their properties related to amenability (growth, absence of free subgroups, amenability of the associated groupoids of germs, etc.).
  15:00 - 15:50: Mark Sapir (Vanderbilt): Asymptotic cones of amenable groups
  16:10 - 17:00: Mark Pollicott (Warwick): Lyapunov exponents for products of positive matrices
• Tuesday, July 10, 2007
  11:00 - 11:50: Volodymir Nekrashevych, II
  15:00 - 15:50: Alex Eskin (Chicago): Quasi-isometries, coarse differentiation and amenability
