Abstract: 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.
My Bio: Jian Wang is currently J.H.Simons' lecturer at Stony Brook University. He obtained his Ph.D. at Institut Fourier with G\'erard Besson, before going to Augsburg for a postdoc. His current research interest is to connect scalar curvature with topological invariants and geometric invariants.
