On the tree cover number and the positive semidefinite maximum nullity of a graph

Chassidy Bozeman

For a simple graph $G = (V, E),$ let $S_{+} (G)$ denote the set of real positive semidefinite matrices $A = (a_{ij})$ such that $a_{ij} \neq = 0$ if ${i, j} \in E$ and $a_{ij} = 0$ if…

Lower Bounds for the Exponential Domination Number of $C_{m} \times C_{n}$

Chassidy Bozeman, Joshua Carlson, Michael Dairyko +2

A vertex $v$ in a porous exponential dominating set assigns weight $(\frac{1}{2})^{d i s t (v, u)}$ to vertex $u$ . A porous exponential dominating set of a graph $G$ is a su…
