SUMMARY:On the Gibbs states of the Ising and Potts models - Loren Coquille

DESCRIPTION:I will first review what is known about the set of Gibbs state
 s of the Ising and Potts models\, mentioning recent joint work with H. Dum
 inil-Copin\, D. Ioffe and Y. Velenik for the 2d case. A natural question (
 open in general) is to determine whether any Gibbs state is weak limit of 
 finite-volume measures with deterministic boundary conditions. I will give
  a counter-example in the 3d Ising case\, and point out what the issues ar
 e in order to extend it to the Potts model. I'll end with a few conjecture
 s.
