Kristin Heysse, Macalaster CollegeKristin Heysse, Macalaster CollegeEwing 336Title: What the Distance Spectrum Knows <br></br> Abstract:The distance matrix of a connected graph is the symmetric matrix with columns and rows indexed by the vertices and entries that are the pairwise distances between the corresponding vertices. Originally considered to solve vertex addressing problems, the distance matrix has taken a place among the more familiar matrices in spectral graph theory. In this talk, we’ll consider what the spectrum of the distance matrix tells us about the graph, how cospectral constructions can help us better understand what the spectrum cannot tell us about the graph, and what elementary graph properties are still in question. 5/1/2018 7:30:00 PM5/1/2018 8:30:00 PMFalse
