Title: On almost all matroids
| Speaker: | Peter Nelson |

| Room: | MC 5417 |
Abstract: I will (for real this time) discuss a recent paper of Pendavingh and Van der Pol that resolved several natural, long-standing conjectures about the properties of almost all matroids. Namely, for some m that is polylogarithmic in n, almost all matroids on n elements are m-connected and have the rank-m self-dual uniform matroid as a minor.

Abstract: We use number theory to derive necessary conditions for
local uniform mixing on bipartite graphs.

Title: Graphs and Faces
| Speaker: | Chris Godsil |
| Affiliation: | University of Waterloo |
| Room: | MC 6486 |
Abstract: Each eigenspace of the adjacency matrix of a graph gives
rise to a polytope. I will discvuss the relations between properties
of the graph and the geometry of the polytope.
