Groups and Combinatorics Seminar
Carmen Amarra (UWA)
will speak on
Symmetric graphs of diameter 2 arising from the classical groups
at 12noon Tuesday 22nd June in MLR2
Abstract: Let V be a vector space of dimension d over a field of q elements, and let
H be an irreducible subgroup of GL(V). Let S be an Horbit consisting of
nonzero vectors, satisfying S = S, and let Gamma= Cay(V,S). Then
Gamma is Gsymmetric, where G = V
times H. Our goal is to find the
graphs Cay(V,S) which have diameter 2, that is, those for which V is
contained in S+S. In particular, we shall consider the case where H is a
classical group.
All welcome.
