Understanding angular momentum in General Relativity

Conserved quantities â mass, linear momentum, center of mass, and angular momentum â are important in various areas of physics as in many cases they provide an essential characterization of a physical system. The concepts of mass and linear momentum are by now well-established in General Relativity, and recently there has been a lot of progress in understanding the center of mass of isolated systems. However, we believe that the somewhat more mysterious notion of angular momentum deserves more attention. In this talk we will discuss the key geometric ideas behind this notion and outline the questions that our team plans to address.Non UBCUnreviewedAuthor affiliation: Uppsala universityResearche
