How Appropriate Are the Gravitational Entropy Proposals for Traversable Wormholes? [PDF]

open access: yesGeneral Relativity and Gravitation, 2022
In this paper we have examined the validity of some proposed definitions of gravitational entropy (GE) in the context of traversable wormhole solutions of the Einstein field equations.

Gravitational Entropy of Hayward Black Hole

open access: yesAnnals of Physics, 2023
We analyze the gravitational entropy defined by the Weyl curvature for the Hayward black hole, which is one of the regular black holes without singularity in the event horizon. Using the definition by the ratio of the Weyl curvature scalar and the Kretschmann scalar as the entropy measure, we evaluate the gravitational entropy on the outer and inner ...

The Entropy of a Gravitating Body

Moscow University Physics Bulletin, 2020
This paper proposes a generalization of the dependence for the entropy of ‘‘ordinary’’ massive bodies with a relatively small entropy of the event horizon of the covering surface to the case of black holes (BH). By doing this, the nature of the famous Bekenstein bound, that is, the universal limit for entropy, is immediately explained and corrections ...
