Interior Structure of a Charged Spinning Black Hole in $(2+1)$-Dimensions

TL;DR

This paper demonstrates that mass inflation occurs in a rotating charged black hole within (2+1) dimensions, showing divergence of the mass function similar to higher-dimensional cases, thus extending understanding of black hole interior dynamics.

Contribution

It extends the concept of mass inflation to (2+1)-dimensional charged spinning black holes, providing a new perspective on their internal structure and dynamics.

Findings

Mass inflation occurs in (2+1)-dimensional rotating black holes.

The mass function diverges similarly to higher-dimensional cases.

The study extends black hole interior analysis to lower dimensions.

Abstract

The phenomenon of mass inflation is shown to occur for a rotating black hole. We demonstrate this feature in $(2+1)$ dimensions by extending the charged spinning BTZ black hole to Vaidya form. We find that the mass function diverges in a manner quantitatively similar to its static counterparts in $(3+1)$, $(2+1)$ and $(1+1)$ dimensions.
