|Groups and Combinatorics Seminar: s-geodesic transitive graphs
Groups and Combinatorics Seminar
Wei Jin (UWA)
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.
