Hebrew University Amitsur Algebra Seminar ***************************** Time: Thursday, December 16, 12:00 Place: room 209, Math building Speaker: Lior Rosenzweig (HUJI) Title: Splitting fields of characteristic polynomials of random elements in arithmetic groups Abstract: I will review a recent result of Jouve Kowalski and Zywina <(http://arxiv.org/abs/1008.3662).> In this paper they give a description of a "generic" Galois group of a random element in an arithmetic subgroup A of connected linear group G defined over a field k. They show that given a random walk on the Cayley graph of A the probability that the Galois group is (at least in the reductive, split case) isomorphic to the Weyl group of G. You are cordially invited! <http://math.huji.ac.il/amitsur.html> --------------------------------------------------------- Technion Math Net-2 (TECHMATH2) Editor: Michael Cwikel <techm@math.technion.ac.il> Announcement from: Gili Schul <gili.schul@mail.huji.ac.il>
