Characterizing cospectral vertices via isospectral reduction
Mark Kempton, John Sinkovic, Dallas Smith +1
Two emerging topics in graph theory are the study of cospectral vertices of a graph, and the study of isospectral reductions of graphs. In this paper, we prove a fundamental relati…
Large scale Ricci curvature on graphs
Mark Kempton, Gabor Lippner, Florentin Munch
We define a hybrid between Ollvier and Bakry Emery curvature on graphs with dependence on a variable neighborhood. The hexagonal lattice is non-negatively curved under this new cur…
Spanning 2-Forests and Resistance Distance in 2-Connected Graphs
Wayne Barrett, Emily J. Evans, Amanda E. Francis +2
A spanning 2-forest separating vertices and of an undirected connected graph is a spanning forest with 2 components such that and are in distinct components. Aside…
