Description

In their seminal 1992 paper, Bañados, Teitelboim and Zanelli (BTZ) proposed a simple charged generalization of what is now known as the spinning BTZ black hole. However, it soon became clear that this spacetime does not satisfy Maxwell equations and was thus discarded. In this talk, we will see that this incorrect original BTZ metric can actually be redeemed - it can be interpreted as a solution of recently discovered Deshpande-Lunin theory which enables us to construct charged and spinning black holes in all odd dimensions by slightly modifying the action with special topological term.
