A Quasi-Local Mass in General Relativity

via

Overview

Watch a theoretical physics seminar where Aghil Alaee from Clark University presents groundbreaking research on a new gauge-independent quasi-local mass and energy concept in general relativity. Explore how this novel approach differs from existing quasi-local masses by featuring a direct quasi-local proof of positivity for spacelike surfaces of any topology. Learn about the concept's asymptotic behaviors at null and spatial infinity of asymptotically flat spacetimes, and understand its rigidity properties in relation to Minkowski space embeddings. Discover the collaborative findings of this research conducted with M. Khuri and S.T. Yau, which advances our understanding of mass and energy measurements in general relativity.
