One-loop partition function of three-dimensional flat gravity

arXiv:1502.06185 · doi:10.1007/JHEP04(2015)178

Abstract

In this note we point out that the one-loop partition function of three-dimensional flat gravity, computed along the lines originally developed for the anti-de Sitter case, reproduces characters of the BMS3 group.
