Title: Graph covers with two new eigenvalues
| Speaker: | Olha Silina |
| Affiliation: | University of Waterloo |
| Room: | MC 5479 |
Abstract:
I am going to talk about graph covers. If $Y$ is a cyclic cover of $X$, it turns out that $Y$ has the same spectrum as $X$ plus (possibly) some new eigenvalues.
