Extreme least singular values of random row submatrices with bounded-density subgaussian entries

Xiufan Yang, Shu Wen, Yitzchak Shmalo

Let $\xi$ be a centered real subgaussian random variable with positive variance and a bounded Lebesgue density, and let $A_m\in {\mathbb{R}}^{N_m\times m}$ have independent entries dist…
