Combinatorial and Algebraic Properties of Nonnegative Matrices

Jenish C. Mehta

We study the combinatorial and algebraic properties of Nonnegative Matrices. Our results are divided into three different categories. 1. We show a quantitative generalization of th…

Edge Expansion and Spectral Gap of Nonnegative Matrices

Jenish C. Mehta, Leonard J. Schulman

The classic graphical Cheeger inequalities state that if $M$ is an $n \times n$ symmetric doubly stochastic matrix, then \[ \frac{1-λ_{2}(M)}{2}\leqϕ(M)\leq\sqrt{2\cdot(1-λ_{2}(M))}…
