PIRSA:19110102  ( MP4 Medium Res , MP3 , PDF ) Which Format?
Central extension and black hole entropy
Speaker(s): Lin-Qing Chen
Abstract: Recent developments on asymptotic symmetries and soft modes have deepened our understanding of black hole entropy and the information paradox. The asymptotic symmetry charge algebra of certain classes of spacetimes could have a nontrivial central extension, which plays a crucial role in black hole ... read more

Central extension in gravity
Speaker(s): Lin-Qing Chen
Abstract: The asymptotic symmetry charge algebra of certain class of spacetimes could have a nontrivial central extension, which measures the non-equivariance of the charges of the large gauge transformations. The Cardy formula of the dual CFT has been famously used to derive black hole entropy. However, it r... read more
