Polymer Partition Functions and the Geometric RSK Correspondence

Polymer Partition Functions and the Geometric RSK Correspondence

Explore the geometric lifting of the RSK correspondence (gRSK) in this 52-minute lecture by Ivan Corwin from Columbia University. Delve into two key results: the invariance of partition functions for directed path ensembles under gRSK, and the discrete Gibbs field structure of the geometric Q-tableaux arising from applying gRSK to inverse-gamma random variable arrays. Gain insights into asymptotic algebraic combinatorics and its applications in polymer physics and stochastic processes.
