Interlacing Polynomial Method for Matrix Approximation via Generalized Column and Row Selection

Jian-Feng Cai, Zhiqiang Xu, Zili Xu

This paper delves into the spectral norm aspect of the Generalized Column and Row Subset Selection (GCRSS) problem. Given a target matrix $A \in R^{n \times d}$ , th…

The minimizers of the $p$ -frame potential

Zhiqiang Xu, Zili Xu

For any positive real number $p$ , the $p$ -frame potential of $N$ unit vectors $X := {x_{1}, \dots, x_{N}} \subset R^{d}$ is defined as ${\rm FP}_{p,N,d}(X)=\sum_{i\…
