Eigenvalues of Brownian Motions on $GL (N, C)$

Tatiana Brailovskaya, Nicholas A. Cook, Todd Kemp +1

We prove that the empirical law of eigenvalues of Brownian motion on the Lie Group $GL (N, C)$ converges almost surely to a deterministic probability measure, chara…

Matrix Random Walks and the Lima Bean Law

Bruce K. Driver, Brian C. Hall, Ching Wei Ho +4

A matrix random walk is a stochastic process of the form $B_{k} = (I + A_{1}) \dots (I + A_{k})$ where $A_{j}$ are independent ``step'' matrices in $M_{N} (C)$ . With the right en…

The spectrum of a tensor of random and deterministic matrices

Félix Parraud

We consider operator-valued polynomials in Gaussian Unitary Ensemble random matrices and we show that its $L^{p}$ -norm can be upper bounded, up to an asymptotically small error, by t…

Asymptotic expansion of smooth functions in deterministic and iid Haar unitary matrices, and application to tensor products of matrices

Félix Parraud

Let $U^{N}$ be a family of $N \times N$ independent Haar unitary random matrices and their adjoints, $Z^{N}$ a family of deterministic matrices, and $P$ a self-adjoint noncommutative po…

Felix Parraud

Let $X^{N}$ be a family of $N \times N$ independent GUE random matrices, $Z^{N}$ a family of deterministic matrices, $P$ a self-adjoint non-commutative polynomial, that is for any $N$ ,…

On the operator norm of non-commutative polynomials in deterministic matrices and iid Haar unitary matrices

Félix Parraud

Let $U^{N} = (U_{1}^{N}, \dots, U_{p}^{N})$ be a d-tuple of $N \times N$ independent Haar unitary matrices and $Z^{N M}$ be any family of deterministic matrices in $\mathbb{M}_N(\mathbb{C})\oti…
