Negative potentials and collapsing universes
Roberto Giambò, John Miritzis, Koralia Tzanni
We study Friedmann--Robertson--Walker models with a perfect fluid matter source and a scalar field nonminimally coupled to matter. We prove that a general class of bounded from abo…

Coupled quintessence with double exponential potentials
Koralia Tzanni, John Miritzis
We study flat Friedmann-Robertson-Walker (FRW) models with a perfect fluid matter source and a scalar field non minimally coupled to matter having a double exponential potential. I…
