Cosmological bounce and Genesis beyond Horndeski (1705.06626v2)
Published 18 May 2017 in hep-th and gr-qc
Abstract: We study a "classical" bouncing scenario in beyond Horndeski theory. We give an example of spatially flat bouncing solution that is non-singular and stable throughout the whole evolution. The model is arranged in such a way that the scalar field driving the cosmological evolution initially behaves like full-fledged beyond Horndeski, whereas at late times it becomes a massless scalar field minimally coupled to gravity.
