Title: Perturbing strongly regular graphs
Speaker: | Chris Godsil |
Affiliation: | University of Waterloo |
Location: | MC 6486 |
Abstract:
We will study the behaviour of the spectrum of a strongly regular graph when we change the weight of an edge. One consequence will be a proof that all the graphs we get from a strongly regular graph by deleting one edge are cospectral.
