Tel Aviv University Dear all, This week at the Horowitz seminar on Probability, Ergodic Theory and Dynamical Systems at Tel Aviv University we are happy to have: Speaker: Noam Berger, The Hebrew University of Jerusalem Title: New conditions for ballisticity for RWRE Date: Monday, March 12 Time: 14:30 Place: Schreiber 309 Abstract: In 2000, Sznitman proved that a uniformly elliptic RWRE is ballistic if a certain back-stepping probability decays exponentially. Later he weakened this condition to stretched exponential decay. In the talk I will show that in dimensions four and higher, the condition can be relaxed to (high degree) polynomial decay. All terminology will be explained in the talk. Based on joint work with Drewitz (Zurich) and Ramirez (Santiago de Chile).
