Consider a sequence of Gibbsian line ensemble whose lowest labeled curve (i.e., the edge) has tight one-point marginals. Then, given certain technical assumptions on the nature of the Gibbs property and underlying random walk measure, we prove that the entire spatial process of the edge is tight. We then apply this black-box theory to the log-gamma polymer Gibbsian line ensemble which we construct. The edge of this line ensemble is the transversal free energy process for the polymer, and our…

We prove that the free energy of the log-gamma polymer between lattice points (1, 1) and (M,N) converges to the GUE Tracy-Widom distribution in the M1/3 scaling, provided that N/M remains bounded
