Energy issue for a class of modified higher order gravity black hole solutions

Abstract: In the case of a large class of static, spherically symmetric black hole solutions in higher order modified gravity models, an expression for the associated energy is proposed and identified with a quantity proportional to the constant of integration, which appears in the explicit solution. The identification is achieved making use of derivation of the First Law of black hole thermodynamics from the equations of motion, evaluating independently the entropy via Wald method and the Hawking temperature via quantu… Show more

“…In Ref. [24], for a particular class of BH solutions, an identification for the BH energy has been proposed, as a quantity proportional to the unique constant of integration which appears in the explicit solutions of FðRÞ-modified gravity models in vacuum. This identification was achieved by making use of a derivation of the first law of black hole thermodynamics from the equations of motion of FðRÞ gravity, by independently evaluating the entropy via the Wald method [25] and the Hawking temperature [26] via quantum mechanical methods in curved space-times.…”
