NOTE CHANGE OF VENUE. The Weizmann Institute of Science Faculty of Mathematics and Computer Science Geometric Functional Analysis and Probability Seminar Lecture Hall, Room 1, Ziskind Building NOTE CHANGE OF VENUE on Wednesday, February 27, 2013 11:00 - 13:00 Tal Orenshtein will speak on Zero-one law for directional transience for one dimensional excited random walks Abstract: We will show that for an excited random walk in one dimension, the probability for right transience is either zero or one. This solves a problem posed by Kosygina and Zerner. Joint with Gidi Amir and Noam Berger. --------------------------------------------------------- Technion Math Net-2 (TECHMATH2) Editor: Michael Cwikel <techm@math.technion.ac.il> Announcement from: Gady Kozma <gady.kozma@weizmann.ac.il>
