Inflationary Behaviour in Axial-symmetric Gravitational Collapse

TL;DR

This paper demonstrates that the interior of charged, spinning black holes formed through axially symmetric collapse is unstable to inflation of mass and angular momentum, with implications extending from (2+1) to (3+1) dimensions.

Contribution

It shows that black hole interiors are unstable to inflation of mass and angular momentum in axially symmetric collapse, extending results from (2+1) to (3+1) dimensions.

Findings

Black hole interiors exhibit instability to inflation of parameters.

Results derived in (2+1) dimensions are applicable to (3+1) dimensions.

Black holes formed from axially symmetric collapse are prone to internal inflation.

Abstract

We show that the interior of a charged, spinning black hole formed from a general axially symmetric gravitational collapse is unstable to inflation of both its mass and angular momentum parameters. Although our results are formulated in the context of $(2+1)$-dimensional black holes, we argue that they are applicable to $(3+1)$ dimensions.
