Title: Automorphism groups of simple graphs with few vertex-orbits
Time and place: 4pm Friday 13 Sep 2019, Weatherburn LT
Abstract:In this talk we will investigate how to construct automorphism groups of graphs with few vertex orbits. The base case is to construct automorphism groups with 2 vertex orbits. We will see how to describe their group theoretic structure and give hints towards an algorithm for constructing these groups and towards generalizations to more orbits.
If time permits, we will see how to count isomorphism classes of graphs with the same automorphism group using the table of marks.
