Random Perturbation of Low Rank Matrices: Improving Classical Bounds
Sean O'Rourke,Van Vu,Ke Wang +2 more
TL;DR: It is shown that, in this scenario, classical perturbation results, such as Weyl and Davis-Kahan, can be improved significantly and many of the new bounds are close to optimal and also discuss some applications.
Journal ArticleDOI
Products of Independent non-Hermitian Random Matrices
TL;DR: In this paper, the authors consider the product of a finite number of non-Hermitian random matrices with i.i.d. centered entries of growing size and show that the empirical spectral distribution of the properly normalized product converges almost surely to a non-random, rotationally invariant distribution with compact support in the complex plane.
Journal ArticleDOI
Gaussian Fluctuations of Eigenvalues in Wigner Random Matrices
TL;DR: In this paper, the authors studied the fluctuations of eigenvalues from a class of Wigner random matrices that generalize the Gaussian orthogonal ensemble and showed that xk is normally distributed in the limit under the condition that both k and n − k tend to infinity.
Journal ArticleDOI
The Elliptic Law
Hoi H. Nguyen,Sean O'Rourke +1 more
TL;DR: The problem of finding the limiting distribution of the ESD for a large class of random Hermitian matrices whose entries on or above the diagonal are independent was studied in this paper.
Journal ArticleDOI
Eigenvectors of random matrices
Sean O'Rourke,Van Vu,Ke Wang +2 more
TL;DR: The goal of this survey is to provide an up-to-date account on properties of eigenvectors when the matrix (or graph) is random.
