DESCRIPTION:Title: Busemann functions and Gibbs measures in directed polyme
 r models on Z^2 .\n\nAbstract: We consider the model of a nearest-neighbor
  random walk on the planar square lattice in a general iid space-time pote
 ntial\, which is also known as a directed polymer in a random environment.
  We prove results on existence\, uniqueness (and non-uniqueness)\, and the
  law of large numbers for semi-infinite path measures. Our main tools are 
 the Busemann functions\, which are families of stochastic processes obtain
 ed through limits of ratios of partition functions.\n	Based on joint work w
 ith Firas Rassoul-Agha.\n
