Selberg型积分的格路计数渐近性

Asymptotics of Selberg-like integrals by lattice path counting

Marcel Novaes

摘要:

我们得到显式表达式的Jacobi和Laguerre随机矩阵合奏的特征值的概率密度的正整数时刻,在大尺寸的渐近制度。这些密度与Selberg和Selberg-like多维积分密切相关。我们的解决方案的方法是组合的:它包括在枚举的某些类别的格路径相关的解决方案的递归关系。

英文摘要:

We obtain explicit expressions for positive integer moments of the probability density of eigenvalues of the Jacobi and Laguerre random matrix ensembles, in the asymptotic regime of large dimension. These densities are closely related to the Selberg and Selberg-like multidimensional integrals. Our method of solution is combinatorial: it consists in the enumeration of certain classes of lattice paths associated to the solution of recurrence relations.
