Stability of the Einstein static universe in modified theories of gravity
Christian G. Boehmer, Lukas Hollenstein, Francisco S. N. Lobo +1
We present a brief overview of the stability analysis of the Einstein static universe in various modified theories of gravity, like f(R) gravity, Gauss-Bonnet or f(G) gravity, and…
Exact solutions of f(R) gravity coupled to nonlinear electrodynamics
Lukas Hollenstein, Francisco S. N. Lobo
In this work, exact solutions of static and spherically symmetric space-times are analyzed in f(R) modified theories of gravity coupled to nonlinear electrodynamics. Firstly, we re…
Stability of the Einstein static universe in f(R) gravity
Christian G. Boehmer, Lukas Hollenstein, Francisco S. N. Lobo
We analyze the stability of the Einstein static universe by considering homogeneous scalar perturbations in the context of f(R) modified theories of gravity. By considering specifi…
