Title: qtRSK*: A probabilistic dual RSK correspondence for Macdonald polynomials
Abstract: We introduce a probabilistic generalization of the dual Robinson–Schensted–Knuth correspondence, called qtRSK∗, depending on two parameters q and t. This correspondence extends our recently introduced qRSt correspondence and allows the first tableaux-theoretic proof of the dual Cauchy identity for Macdonald polynomials. By specializing q and t, one recovers the row and column insertion version of the classical dual RSK correspondence as well as of q- and t-deformations thereof which are connected to q-Whittaker and Hall–Littlewood polynomials, but also a novel correspondence for Jack polynomials.
The talk is based on joint work with Gabriel Frieden.
