Limiting empirical spectral distribution for the non-backtracking matrix of an Erdős-Rényi random graph
Ke Wang, Philip Matchett Wood
In this note, we give a precise description of the limiting empirical spectral distribution (ESD) for the non-backtracking matrices for an Erdős-Rényi graph assuming te…
Asymptotic Properties of Random Restricted Partitions
Tiefeng Jiang, Ke Wang
We study two types of probability measures on the set of integer partitions of with at most parts. The first one chooses the random partition with a chance related to its l…
Statistical properties of eigenvalues of Laplace-Beltrami operators
Tiefeng Jiang, Ke Wang
We study the eigenvalues of a Laplace-Beltrami operator defined on the set of the symmetric polynomials, where the eigenvalues are expressed in terms of partitions of integers. By…
New Methods for Handling Singular Sample Covariance Matrices
Gabriel H. Tucci, Ke Wang
The estimation of a covariance matrix from an insufficient amount of data is one of the most common problems in fields as diverse as multivariate statistics, wireless communication…
Random covariance matrices: Universality of local statistics of eigenvalues up to the edge
Ke Wang
We study the universality of the eigenvalue statistics of the covariance matrices where is a large matrix obeying condition . In particu…
