Tel Aviv University Dear all, This Monday we will have a special Horowitz seminar at the usual time and place. These will be held irregularly during the summer to accommodate visitors and other special talks. Our first special seminar features Oren Louidor from UCLA. Speaker: Oren Louidor, University of California, Los Angeles Title: Complete Survival for the Biased Voter Model on Regular Trees Date: Monday, July 2 Time: 14:30 Place: Schreiber 309 Abstract: We consider the Biased Voter Model (also known as the Williams Bjerknes model) on the d-regular tree and prove that local survival implies asymptotic consensus (or complete survival). Complete survival and fixation are also considered in the case of general vertex transitive graphs, where the initial configuration is chosen according to a distribution which is automorphism invariant and/or ergodic. Joint work with Ran Tessler and Alexander Vandenberg-Rodes. Have a good summer, Ron Seminar webpage: <http://www.math.tau.ac.il/~peledron/Horowitz_seminar/Horowitz_seminar.html> --------------------------------------------------------- Technion Math Net-2 (TECHMATH2) Editor: Michael Cwikel <techm@math.technion.ac.il> Announcement from: Ron Peled <peledron@gmail.com>
