Comment on ''Understanding the Area Proposal for Extremal Black Hole Entropy''

TL;DR

This paper critiques a recent proposal explaining the entropy of extremal black holes, arguing it relies on singular geometries and neglects regular metrics' contributions in the partition function.

Contribution

It clarifies that the previous approach depends on singular geometries and does not address the role of regular extremal black hole metrics.

Findings

The approach uses strongly singular geometries.

It neglects contributions from regular extremal black hole metrics.

The critique emphasizes the importance of regular metrics in entropy calculations.

Abstract

A. Ghosh and P. Mitra made the proposal how to explain the area law for the entropy of extreme black holes in some model calculations. I argue that their approach implicitly operates with strongly singular geometries and says nothing about the contribution of regular metrics of extreme black holes into the partition function.
