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.

Title: The mathematics of juggling
| Speaker: | Gabriel Gauthier-Shalom |
