Eigenvector statistics of Lévy matrices

چکیده

We analyze statistics for eigenvector entries of heavy-tailed random symmetric matrices (also called Lévy matrices) whose associated eigenvalues are sufficiently small. show that the limiting law any such entry is non-Gaussian, given by product a normal distribution with another variable depends on location corresponding eigenvalue. Although latter typically nonexplicit, median it inverse one-sided stable law. Moreover, we different same asymptotically independent, but there nontrivial correlations between eigenvectors nearby eigenvalues. Our findings contrast sharply known behavior Wigner and sparse graphs.

Eigenvector Statistics of Sparse Random Matrices

We prove that the bulk eigenvectors of sparse random matrices, i.e. the adjacency matrices of ErdősRényi graphs or random regular graphs, are asymptotically jointly normal, provided the averaged degree increases with the size of the graphs. Our methodology follows [6] by analyzing the eigenvector flow under Dyson Brownian motion, combining with an isotropic local law for Green’s function. As an...

Eigenvector statistics of the product of Ginibre matrices.

We develop a method to calculate left-right eigenvector correlations of the product of m independent N×N complex Ginibre matrices. For illustration, we present explicit analytical results for the vector overlap for a couple of examples for small m and N. We conjecture that the integrated overlap between left and right eigenvectors is given by the formula O=1+(m/2)(N-1) and support this conjectu...

Eigenvector Distribution of Wigner Matrices

We consider N×N Hermitian or symmetric random matrices with independent entries. The distribution of the (i, j)-th matrix element is given by a probability measure νij whose first two moments coincide with those of the corresponding Gaussian ensemble. We prove that the joint probability distribution of the components of eigenvectors associated with eigenvalues close to the spectral edge agrees ...

Nonlinear eigenvalue { eigenvector problems for STP matrices

A matrix A is said to be strictly totally positive (STP) if all its minors are strictly positive. STP matrices were independently introduced by Schoenberg in 1930 (see [13, 14]) and by Krein and Gantmacher in the 1930s. The main results concerning eigenvalues and eigenvectors of STP matrices were proved by Gantmacher and Krein in their 1937 paper [6]. (An announcement appeared in 1935 in [5]. C...

Hermitian Matrices, Eigenvalue Multiplicities, and Eigenvector Components

Given an n-by-n Hermitian matrix A and a real number λ, index i is said to be Parter (resp. neutral, downer) if the multiplicity of λ as an eigenvalue of A(i) is one more (resp. the same, one less) than that in A. In case the multiplicity of λ in A is at least 2 and the graph of A is a tree, there are always Parter vertices. Our purpose here is to advance the classification of vertices and, in ...
