Cores of vertex-transitive graphs

at 1 pm Tuesday 17th August in MLR2

Abstract: A homomorphism of two graphs X and Y is a map between the vertex sets V(X) and V(Y) such that f(x) is adjacent to f(y) in Y whenever x and y are adjacent in X. Examples include automorphisms, isomorphisms and retractions, which are homomorphisms from a graph to one of its induced subgraphs (known as a retract). In this talk I will outline my proposed research project, which is to investigate the cores (minimal retracts) of some families of cayley graphs, and will summarise the existing results for the cores of vertex-transitive graphs.

All welcome.
