In this paper, we study the probability distribution of eigenvalues of the n×n Euclidean random matrix whose (i,j)th entry is of the form f(xixj2)unδijkf(xixk2) for some real function f. Random points xi's are independently distributed in the lp ellipsoid or on its surface in RN including the unit sphere SN1, the simplex, the ordinary ellipsoid and the hyper-cube. Here un is allowed to be any real number which includes the two most interesting cases un=0 and un=1. The limits of the empirical distribution of its eigenvalues are derived in two high dimensional settings: n/Nγ(0,) and n/N0 as both n and N go to infinity. By taking f(x) to be suitable functions, we also give the explicit limiting spectral distributions for some distance matrices whose entries are based on the Euclidean distance and the geodesic distance.

从 lp 椭球生成的大欧几里得随机矩阵的谱

在本文中,我们研究了特征值的概率分布n×n欧几里得随机矩阵(一世,j)H条目的形式F(X一世-Xj2)-nδ一世jķF(X一世-Xķ2)对于一些实函数f。随机点X一世的独立分布在lp椭球体或其表面上Rñ包括单位球体小号ñ-1、单纯形、普通椭球和超立方体。这里n允许是任何实数,包括两个最有趣的情况n=0n=1. 其特征值的经验分布的极限是在两个高维设置中得出的:n/ñγ(0,)n/ñ0因为nN都趋于无穷大。通过采取F(X)为了成为合适的函数,我们还给出了一些距离矩阵的显式限制谱分布,这些距离矩阵的条目基于欧几里得距离和测地线距离。
