Invariant Tensions from DCFT

abstract:

I will revisit the problem of defining an invariant notion of brane tension, analogous to the ADM mass, in a theory of gravity. I will propose two natural definitions, a gravitational and an inertial tension, in terms of asymptotic data akin to that of a Defect CFT. I will illustrate these definitions with various examples, and present the evidence why for supersymmetric branes the two tensions must be equal.
