Symmetries of Periodic and Free Boundary q-Whittaker Measures

Abstract. We show that the periodic and free boundary q-Whittaker measures, two models of random partitions, exhibit remarkable distributional symmetries. Equivalently, we derive new identities for skew q-Whittaker functions related to bounded Cauchy and Littlewood identities. These extend identities found by Imamura, Mucciconi, and Sasamoto, and in particular give new proofs of these identities.
