Mass of asymptotically Euclidean manifolds using spinors and 1-forms
Demetre Kazaras
Abstract: The total mass of an asymptotically Euclidean manifold is an invariant from mathematical General Relativity which has fascinated geometers for many decades. In these lectures, we will discus the celebrated Positive Mass Theorem, first describing in some detail the proof by Witten which uses spinors. I will not assume any prior knowledge of spinors. We will then focus on a contemporary approach using 1-forms which arise as the differential of solutions to a certain "spacetime harmonic" equation motivated by recent work by Daniel Stern. This second part contains work by myself, Hugh Bray, Sven Hirsch, Marcus Khuri, and Yiyue Zhang.
