Title: Graphs with three eigenvalues
Speaker: | Gary Greaves |
Affiliation: | Tohoku University |
Room: | MC 6486 |
Abstract: I will present some recent results on graphs having precisely three eigenvalues. In particular, I will present the case when such graphs have only two different valencies and the case when the second largest eigenvalue is at most 1.
