Finite s-Geodesic Transitive Graphs

at 1pm on Tuesday 20th of November in Maths Lecture Room 2

Abstract: A geodesic from a vertex u to a vertex v in a graph is one of the shortest paths from u to v, and this geodesic is called an s-geodesic if the distance between u and v is s.

A graph is said to be s-geodesic transitive if, for each i less than or equal to s, all i-geodesics are equivalent under the group of graph automorphisms. In this talk, I will show the relationship of 2-geodesic transitive graphs with a certain family of partial linear spaces. I will also compare s-geodesic transitivity of graphs with two other well-known transitivity properties, namely s-arc transitivity and s-distance transitivity.

This is a joint work with my supervisors.

All welcome
