Title: Arc-transtive cubic graphs

Speaker: | Krystal Guo |

Affiliation: | University of Waterloo |

Room: | MC 6486 |

Abstract: We will look at a classical result of Tutte in his seminal paper "A Family of Cubic Graphs"; every cubic arc-transitive graph is s-arc-regular for some s between 1 and 5.
