because dark matter and dark energy are replaced by a single fluid that behaves
as the former at early times and as the latter at late times. In this short
paper we analyze... | arxiv topic:gr-qc |

We study countably piecewise continuous, piecewise monotone interval maps. We
establish a necessary and sufficient criterion for the existence of a
nondecreasing semiconjugacy to a map of constant slope in terms of the
