Arithmetic Statistics Seminar: Singularity probability of adjacency matrices of random regular digraphs

SEMINARS

Speaker:

Hoi Nguyen - Ohio State

We will discuss an algebraic method by J. Huang to bound the singularity probability of the adjacency matrix of random d-regular digraphs. Although we can slightly improve the bounds, the current estimates are still far from best possible, especially toward the problem of bounding the least singular values.
