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
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).
Best regards,
