Stability of the Einstein static universe in modified Gauss-Bonnet gravity

CG Boehmer, FSN Lobo - Physical Review D—Particles, Fields, Gravitation …, 2009 - APS
We analyze the stability of the Einstein static universe by considering linear homogeneous
perturbations in the context of f (G) modified Gauss-Bonnet theories of gravity. By …

Exact solutions of gravity coupled to nonlinear electrodynamics

L Hollenstein, FSN Lobo - Physical Review D—Particles, Fields, Gravitation …, 2008 - APS

Stability of the Einstein Static Universe in Gauss-Bonnet Gravity

SL Li, P Wu, H Yu - arxiv preprint arxiv:2004.02080, 2020 - arxiv.org
By rescaling the Gauss-Bonnet (GB) coupling constant $\alpha\rightarrow\alpha/(D-4) $ and
considering the $ D\rightarrow 4$ limit, the GB gravity gives rise to nontrivial modification of …
