3-Manifold Seminar: Hyperbolic 4-manifolds with trivial Seiberg-Witten invariants
Seminar | April 2 | 3:40-5 p.m. | 736 Evans Hall
Ian Agol, UC Berkeley
We'll describe subgroup separability for arithmetic hyperbolic manifolds of simplest type and apply it to describe embedding results due to Kolpakov-Reid-Slavich. With this we can address a conjecture of Claude LeBrun that the Seiberg-Witten invariants of hyperbolic 4-manifolds vanish, by showing the existence of examples for which it is true. Joint with Francesco Lin.
