Comment on "Horizon area- Angular momentum inequality for a class of axially symmetric black holes" [arXiv:1012.2413]

TL;DR

This paper extends previous results on black hole inequalities to axisymmetric, maximal initial data invariant under inversion, broadening the scope of the original findings.

Contribution

It generalizes the horizon area-angular momentum inequality to a new class of axisymmetric initial data with inversion symmetry.

Findings

Extended inequality to inversion-invariant data

Broadened understanding of black hole initial data

Provided mathematical framework for new symmetry class

Abstract

We extend the results presented by Ace\~na \textit{et al} in the afore mentioned paper, [arXiv:1012.2413], to the case of axisymmetric, maximal initial data which are invariant under an inversion transformation.
