Static Black Holes and Iyer-Wald Entropy in Gravity
I. DÃaz-Saldaña, J. López-DomÃnguez, Wilfredo Yupanqui +3
We investigate static, spherically symmetric black hole solutions in a class of higher-curvature gravitational theories described by a Lagrangian that depends on the Ricci and Kret…

Observational constraints on entropic cosmology
Javier Chagoya, I. DÃaz-Saldaña, Mario H. Amante +2
In this work, we derive a generalized modified Friedmann equation based on an entropy-area relation that incorporates established modifications, such as volumetric, linear, and log…

Cosmic acceleration in entropic cosmology
Javier Chagoya, I. DÃaz-Saldaña, J. C. López-DomÃnguez +1
In this paper we study the viability of an entropic cosmological model. The effects of entropic gravity are derived from a modified entropy-area relationship with a volumetric entr…
