On spectrum of sample correlation matrices from large fold tensor vectors

Wangjun Yuan

In this paper, we investigate the limiting spectral distribution of the sample correlation matrix, whose sample vectors are $k$ -fold tensor products of $n$ -dimensional vectors with…

Stochastic partial differential equations associated with Feller processes

Jian Song, Meng Wang, Wangjun Yuan

For the stochastic partial differential equation $\frac{\partial u}{\partial t} = L u + u W ˙$ where $W ˙$ is Gaussian noise colored in time and $L$ is the infi…

Operator Norm Bounds for Multi-leg Matrix Tensors and Applications to Random Matrix Theory

BenoÃ®t Collins, Wangjun Yuan

We investigate the extremal values of partial traces of matrix tensors under operator norm constraints. To evaluate these multi-linear quantities, we develop a comprehensive graphi…
