Local laws for multiplication of random matrices

Xiucai Ding, Hong Chang Ji

Consider the random matrix model $A^{1/2} U B U^{*} A^{1/2},$ where $A$ and $B$ are two $N \times N$ deterministic matrices and $U$ is either an $N \times N$ Haar unitary or orthogonal…

Edge statistics of large dimensional deformed rectangular matrices

Xiucai Ding, Fan Yang

We consider the edge statistics of large dimensional deformed rectangular matrices of the form $Y_{t} = Y + t X,$ where $Y$ is a $p \times n$ deterministic signal matrix whose rank…
