Positive energy of topologically massive gravity

Deser, S. ORCID icon

Abstract

I review how 'classical SUGRA' embeddability establishes positive energy for D = 3 topologically massive gravity, with or without a cosmological term, by a procedure familiar from D = 4 Einstein gravity (GR). This method also provides explicit energy expressions. In contrast to GR, it is not manifestly positive here, due to this theory's peculiar two-term nature.
