Title: Critical groups of graphs.
Abstract: The critical group of a graph is an interesting isomorphic
invariant. It is a finite abelian group whose order is equal to the number
of spanning forests in the graph. The Smith normal form of the graph's
Laplacian determines the structure of its critical group. In this
presentation, we will consider a family of strongly regular graphs. We
will apply representation theory of groups of automorphisms to determine
the critical groups of graphs in this family
