紧李群的矩阵积分和张量不变量的渐近性

Asymptotics of matrix integrals and tensor invariants of compact Lie groups

Michael Stolz, Tatsuya Tate

摘要:

本文给出了一个矩阵积分的渐近公式,它在Diaconis等人的随机矩阵特征值方法中起着至关重要的作用。渐近分析的参数的选择是由这种类型的积分不变的理论解释的动机。对于任意连通半单紧李群的任意正则不可约表示,得到了某些算子在张量不变量空间上迹的渐近公式,从而推广了Biane关于这类空间维数的一个结果.

英文摘要:

In this paper we give an asymptotic formula for a matrix integral which plays a crucial role in the approach of Diaconis et al. to random matrix eigenvalues. The choice of parameter for the asymptotic analysis is motivated by an invariant theoretic interpretation of this type of integral. For arbitrary regular irreducible representations of arbitrary connected semisimple compact Lie groups, we obtain an asymptotic formula for the trace of certain operators on the space of tensor invariants, thus extending a result of Biane on the dimension of these spaces.
