Spectra of random regular hypergraphs

Ioana Dumitriu, Yizhe Zhu

In this paper, we study the spectra of regular hypergraphs following the definitions from Feng and Li (1996). Our main result is an analog of Alon's conjecture for the spectral gap…

On expansion of $G_{n, d}$ with respect to $G_{m, d}$

Ioana Dumitriu, Mary Radcliffe

In several works, Mendel and Naor have introduced and developed theory surrounding a nonlinear expansion constant similar to the spectral gap for sequences of graphs, in which one…

Path counting and random matrix theory

Ioana Dumitriu, Etienne Rassart

We establish three identities involving Dyck paths and alternating Motzkin paths, whose proofs are based on variants of the same bijection. We interpret these identities in terms o…
