Mark Kac Seminar 2009-2010

March 5, 2010

11:15-13:00	speaker: Erwin Bolthausen (Zürich)	title: On the ultrametricity problem in spin glass theory
	abstract: Ultrametricity is perhaps the main open problem in mean-field spin glasses. We given an overview about the problem, and report on some of the attempts to understand it, partly by analyzing toy models.
14:15-16:00	speaker: Yvan Velenik (Genève)	title: Statistical Physics of stretched polymers
	abstract: I'll return, in more detail, to the description of properties of stretched polymers already discussed in Lecture #1. I'll then discuss some related questions, in particular: (i) the order of the phase transition in the selfattractive case, and (ii) applications to (non-directed) polymers in quenched random environment. This is based on joint works with D. Ioffe.. Additional material: Find here the slides of Velenik's first lecture on Feb 5.
