2022 NCTS Workshop on Mathematical General Relativity

Overview

Due to the equivalence principle and the lack of an absolute space, the understanding of the fundamental notion of mass and angular momentum has been subtle since Einstein's time. In the 80’s, Rick Schoen and S.-T. Yau showed that the so-called ADM mass of an isolated physical system can never be negative. Since then, the subject has undergone rapid developments. In particular, many new ideas and techniques from geometric analysis were applied and major progress has been achieved. Questions from this subject also stimulate the researches in differential geometry.

The Schoen--Yau “positive mass theorem” constituted an essential first step for defining “quasi-local” physical quantities. The talks of this workshop will introduce recent developments on the mathematics of mass and angular momentum.
