Asymptotics of qPlancherel measures
Abstract
In this paper, we are interested in the asymptotic size of rows and columns of a random Young diagram under a natural deformation of the Plancherel measure coming from Hecke algebras. The first lines of such diagrams are typically of order $n$, so it does not fit in the context studied by P. Biane and P. Śniady. Using the theory of polynomial functions on Young diagrams of Kerov and Olshanski, we are able to compute explicitly the first and secondorder asymptotics of the length of the first rows. Our method works also for other measures, for instance those coming from SchurWeyl representations.
