DESCRIPTION:Title: Universality of directed polymers in the intermediate di
 sorder regime.\n\nAbstract: In 2018\, Krishnan and Quastel showed that the
  fluctuations of Seppäläinen's log-gamma polymer converge in law to the Tr
 acy-Widom GUE distribution in the intermediate disorder regime. This regim
 e corresponds to taking the inverse temperature $\beta$ to depend on the l
 ength of the polymer $2n$\, with $\beta=n^{-\alpha}$ for some $\alpha<1/4$
 . They also conjectured that this should hold for random directed polymers
  with general i.i.d weights. In this talk\, I will sketch a proof of their
  conjecture for $1/5<\alpha<1/4$\, using a kind of “local chaos expansion”
 .niversality of directed polymers in the intermediate disorder regime.\n\n
