Comments on deformed phase-space cosmology, SUSY and black holes
O. López-Aguayo, J. C. López-DomÃnguez, G. E. Pérez-Cuéllar +1
This paper presents the construction of the supersymmetric (SUSY) deformed version of the time dependent metric that describes the interior of the Schwarzschild BH. First, the nonc…
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…
S-Duality and Categorical Gauge Theory
Javier Chagoya, A. D. López-Hernández, M. Sabido
In this work, we revisit abelian S-duality in the context of higher gauge theory. By using a specific crossed module a set of transformations arise, which are known as the "thin" a…
On planetary orbits, ungravity and entropic gravity
G. Pérez Cuéllar, M. Sabido
In previous works, entropic gravity and ungravity have been considered as possible solutions to the dark energy and dark matter problems. To test the viability of these models, mod…
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…
