摘要
The mass is a fundamental global geometric invariant. In this talk, we will present a mass inequality for asymptotically locally flat (ALF) 4-manifolds and explore its connections to some Ricci-flat 4-manifolds called ALF gravitational instantons. We will also discuss recent progress on their classification.

Jian Wang is a faculty member at the Academy of Mathematics and Systems Sciences, Chinese Academy of Sciences. He received his Ph.D. from Institut Fourier under the supervision of Gérard Besson, and subsequently held a postdoctoral position at Augsburg. He later served as a Simons Instructor at Stony Brook University. His current research focuses on connections between scalar/Ricci curvature and topological as well as geometric invariants.
