DESCRIPTION:Speaker: Jean-Christophe Mourrat\nhosted by M. Beiglböck\, N. 
 Berestycki\, L. Erdös\, J. Maas\, F. Toninelli\nAbstract: Spin glasses ar
 e models of statistical mechanics encoding disordered interactions between
  many simple units. One of the fundamental quantities of interest is the f
 ree energy of the model\, in the limit when the number of units tends to i
 nfinity. For a restricted class of models\, this limit was predicted by Pa
 risi\, and later rigorously proved by Guerra and Talagrand. I will first s
 how how to rephrase this result using an infinite-dimensional Hamilton-Jac
 obi equation. I will then present partial results suggesting that this new
  point of view may allow to understand limit free energies for a larger cl
 ass of models\, focusing in particular on the case in which the units are 
 organized over two layers\, and only interact across layers.
