Spiked multiplicative random matrices and principal components

X Ding, HC Ji - Stochastic Processes and their Applications, 2023 - Elsevier
In this paper, we study the eigenvalues and eigenvectors of the spiked invariant
multiplicative models when the randomness is from Haar matrices. We establish the limits of …

Berry-Esseen bounds for the multivariate ℬ-free CLT and operator-valued matrices

M Banna, T Mai - Transactions of the American Mathematical Society, 2023 - ams.org
We provide bounds of Berry-Esseen type for fundamental limit theorems in operator-valued
free probability theory such as the operator-valued free Central Limit Theorem and the …

On the spectral edge of non-Hermitian random matrices

A Campbell, G Cipolloni, L Erdős, HC Ji - arXiv preprint arXiv:2404.17512, 2024 - arxiv.org
For general non-Hermitian random matrices $ X $ and deterministic deformation matrices $
A $, we prove that the local eigenvalue statistics of $ A+ X $ close to the typical edge points …

Outliers and bounded rank perturbation for non-Hermitian random band matrices

Y Han - arXiv preprint arXiv:2408.00567, 2024 - arxiv.org
In this work we consider general non-Hermitian square random matrices $ X $ that include a
wide class of random band matrices with independent entries. Whereas the existence of …
