Apparent horizon thermodynamics in an exponential gravity model
A. Oliveros, Ivan R. Vasquez
We investigate the thermodynamics of the apparent horizon in an exponential gravity model characterized by the two parameters and , within a spatially flat Friedmann-…

Phase space analysis of an exponential model in gravity including linear dark-sector interactions
Ivan R. Vasquez, A. Oliveros
We present a cosmological analysis of an exponential gravity model, within the dynamical systems formalism. Following the method introduced by Böhmer \textit{et al} [Univer…

Overspinning problem in Kerr black holes: second order corrections and self-energy
Ivan R. Vasquez
We consider gedanken experiments to destroy Kerr black holes by means of absorbing matter with sufficient energy and angular momentum. It is shown that extremal and near-extremal K…
