Comment on `Black hole entropy and isolated horizon thermodynamics'

TL;DR

This paper critiques the model-dependent thermodynamic analysis of black holes, highlighting its inability to determine microcanonical entropy and discussing additional issues in the methodology.

Contribution

It identifies fundamental limitations in existing black hole thermodynamics models, emphasizing the need for more comprehensive approaches.

Findings

Canonical entropy can be obtained, but microcanonical entropy cannot.

Several methodological problems are discussed.

Highlights the importance of model independence in black hole thermodynamics.

Abstract

There is a deep underlying problem in the model dependent thermodynamic analysis of black holes shown in the above quoted paper. In this method one can only find out the canonical entropy of the black hole but not the `microcanonical' entropy. Besides this crucial issue a few other problems are also discussed.
