Tel Aviv University Hello everyone, The last colloquium talk of the semester will be held on Monday, 6/6/2011, 12:15, Schreiber 006, Tel Aviv University. The speaker is Eyal Lubetzky (Microsoft Research) and the title of his talk is The static and stochastic Ising models The abstract is given below. Tea and coffee at 12:00, same room. Hope to see you there. For information about past colloquiua, see <http://www.math.tau.ac.il/~klartagb/colloq_2010.html> You are all welcome to suggest colloquium speakers for the next academic year. Yours, Bo'az ------------------------- Abstract: The Ising model, one of the most studied models in mathematical physics, was introduced in 1925 to model ferromagnetism. In the classical 2D setting, the model assigns plus/minus spins to the sites of the square grid according to a given probability distribution, which is a function of the number of neighboring sites whose spins agree, as well as the temperature. Over the last three decades, significant effort has been dedicated to the analysis of stochastic dynamical systems that both model the evolution of the Ising model and provide efficient methods for sampling from it. In this talk I will survey the rich interplay between the behaviors of the static and the dynamical models as they both undergo a phase transition at the critical temperature. In particular I will discuss a fundamental problem on the dynamical model introduced by Glauber in 1963, which we recently settled in joint work with Allan Sly. --------------------------------------------------------- Technion Math Net-2 (TECHMATH2) Editor: Michael Cwikel <techm@math.technion.ac.il> Announcement from: <klartagb@post.tau.ac.il>
