Aim & Scope:

Due to the equivalence principle and the lack of an absolute space, the understanding of this fundamental notion for gravitation has been subtle since Einstein's time. Arnowitt-Deser-Misner gave the well-defined definition for an asymptotically flat isolated system, while Bondi-Trautman gave the definition of mass after gravitational radiation. By 1970's, it was well-recognized that the positivity of these notions, which is intimately related to the stability of the system, lies in the foundation of the theory of general relativity. There was an intense period of study and the efforts culminated in the proof of the positive mass theorem by Schoen-Yau in 1980's (a different proof was given by Witten later). The subject has since undergone rapid developments. In particular, many new ideas and techniques from geometric analysis were applied and major progress has been achieved. The talks of this workshop will provide an overview of related topics and also make connections to the summer course "The mathematics of gravitational radiations" in the following week.
