Analyticity of Event Horizons of Five-Dimensional Multi-Black Holes with Non-Trivial Asymptotic Structure

TL;DR

This paper demonstrates that five-dimensional multi-black hole solutions with non-trivial asymptotic structure can have analytic event horizons, contrasting with solutions in asymptotically flat space-time.

Contribution

It establishes the existence of analytic event horizons in five-dimensional multi-black hole solutions with non-trivial asymptotic structure, expanding understanding of black hole horizon regularity.

Findings

Existence of analytic horizons in non-trivial asymptotic structures

Contrast with non-analytic horizons in asymptotically flat space

New class of solutions with regular horizons

Abstract

We show that there exist five-dimensional multi-black hole solutions which have analytic event horizons when the space-time has non-trivial asymptotic structure, unlike the case of five-dimensional multi-black hole solutions in asymptotically flat space-time.
