  • Quasimatter domination parameters in bouncing cosmologies 

    Elizalde, Emilio; Haro Cases, Jaume; Odintsov, Sergei D. (American Physical Society, 2015-03-19)
    Open Access
    A fine set of parameters is introduced for bouncing cosmologies in order to describe the nearly matterdominated phase, and which play the same role that the usual slow-roll parameters play in inflationary cosmology. It is ...

    It has been claimed in a recent paper [J. D. Barrow, A. B. Batista, J. C. Fabris, M. J. S. Houndjo, and G. Dito, Phys. Rev. D 84, 123518 (2011).] that sudden singularities will survive in semiclassical gravity. This issue ...
