q-Plancherel测度的渐近性

Asymptotics of q-Plancherel measures

Valentin Feray, Pierre-Loïc Méliot

摘要:

本文研究了随机Young图在来自Hecke代数的Plancherel测度的自然变形下的行和列的渐近大小。这类图的第一行通常是$n$阶的,因此它不适合P. Biane和P. P. Benniady所研究的上下文。利用Kerov和Olshanski的Young图上的多项式函数理论,我们能够明确地计算第一行长度的一阶和二阶渐近性。我们的方法也适用于其他措施,例如那些来自舒尔-外尔表示。

英文摘要:

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 second-order asymptotics of the length of the first rows. Our method works also for other measures, for instance those coming from Schur-Weyl representations.
