will speak on

s-geodesic transitive graphs

at 11am on Wednesday 4th of April in MLR2.

Abstract: In a finite graph Gamma, a geodesic from a vertex u to a vertex v is one of the shortest paths from u to v, and this geodesic is called an i-geodesic if the distance between u and v is i. The graph Gamma is said to be s-geodesic transitive if the graph automorphism group is transitive on the set of s-geodesics. In this talk, I will compare the s-geodesic transitivity with other two well-known transitive properties, namely s-arc transitivity and s-distance transitivity, and determine the local structure of 2-geodesic transitive graphs, and also give some results about the family of locally disconnected 2-geodesic transitive but not 2-arc transitive graphs.

All welcome
