无限对称群和无限Hecke代数特征标的中心极限定理

A central limit theorem for the characters of the infinite symmetric group and of the infinite Hecke algebra

Pierre-Loïc Méliot

摘要:

本文回顾了无限对称群的表示论,推广了Kerov和Vershik的工作,证明了无限对称群的不可约特征标总是满足一个中心极限定理.因此,对于托马单形的任何点,在杨图的水平上的相应的措施具有高斯浓度的性质。通过使用Robinson-Schensted-Knuth算法和Pitman算子理论,我们将这些结果与由riffle shuffles获得的某些随机排列的性质以及条件为留在Weyl室中的随机游动的行为联系起来。

英文摘要:

In this paper, we review the representation theory of the infinite symmetric group, and we extend the works of Kerov and Vershik by proving that the irreducible characters of the infinite symmetric group always satisfy a central limit theorem. Hence, for any point of the Thoma simplex, the corresponding measures on the levels of the Young graph have a property of gaussian concentration. By using the Robinson-Schensted-Knuth algorithm and the theory of Pitman operators, we relate these results to the properties of certain random permutations obtained by riffle shuffles, and to the behaviour of random walks conditioned to stay in a Weyl chamber.
