Singular vector and singular subspace distribution for the matrix denoising model

Zhigang Bao, Xiucai Ding, Ke Wang

In this paper, we study the matrix denosing model $Y = S + X$ , where $S$ is a low-rank deterministic signal matrix and $X$ is a random noise matrix, and both are $M \times n$ . In the sc…

On the support of the free additive convolution

Zhigang Bao, Laszlo Erdos, Kevin Schnelli

We consider the free additive convolution of two probability measures $μ$ and $ν$ on the real line and show that $μ ⊞ ν$ is supported on a single interval if $μ$ and $ν$ each…
