will speak on
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.
