Stability of Einstein static universe in Eddington-inspire Born-Infeld theory [CL]

http://arxiv.org/abs/1705.06819


By considering the realization of emergent universe scenario in Eddington-inspire Born-Infeld (EiBI) theory, we study the stability of Einstein static universe filled with perfect fluid in EiBI theory against both the homogeneous and inhomogeneous scalar perturbations in this work. We find that in both the spatially flat and closed cases, the emergent universe scenario is no longer viable, since Einstein static universe cannot be stable against both the homogeneous and inhomogeneous scalar perturbations simultaneously. However, the emergent universe scenario survives in the spatially open case, while Einstein static universe can be stable under some conditions.
