Character of the highest weight module of BMS algebra realized on codimensional-two boundary
Bin Chen, Song He, Pujian Mao +1
In this paper, we investigate the highest weight representation (HWR) of the three and four-dimensional Bondi-Metzner-Sachs (BMS) algebra realized on the codimension-two boundary o…
