Positive mass theorem for asymptotically locally flat 4-manifolds with S^1-symmetries

Speaker: Jian Wang, Stony Brook

Location: Warren Weaver Hall 512

Date: Friday, April 19, 2024, 11 a.m.

Synopsis:

The ADM mass, a crucial global geometric invariant, intricately relates with scalar curvature in the different setting. I will explain the relation between asymptotically locally flat (ALF) 4-manifolds and their  ADM mass. Specifically, I will talk about how the topology at infinity influences the ADM mass within the ALF setting.
