DESCRIPTION:Speaker: Clement Cosco\nhosted by M. Beiglböck\, N. Berestycki
 \, L. Erdös\, J. Maas\, F. Toninelli\nAbstract: We consider the model of 
 directed polymers in dimension 1+2\, in the temperature region where the p
 artition function stays bounded in L2. In this regime\, it is known that t
 he diffusively rescaled log-partition function converges to a Gaussian log
 -correlated field. One natural question is to understand the behavior of t
 he maximum of this rescaled field\, which is related to the problem of und
 erstanding the probability distribution of the favorite point of the polym
 er trajectory. One major issue is that the field itself (before taking the
  limit) is not Gaussian\, and one has to quantify how close it is to a Gau
 ssian field. To do so\, one has to compute high moments (going to infinity
  with the volume) of the partition function. I will explain how we were ab
 le to obtain sharp moment estimates and discuss the background and open qu
 estions.Joint work with Ofer Zeitouni.
