Linking little rip cosmologies with regular early universes
Felipe Contreras, Norman Cruz, Emilio Elizalde +2
Cosmological fluids with a Generalized Equation of State (GEoS) are here considered, whose corresponding EoS parameter describes a fluid with phantom behavior, namely , b…

Bouncing solutions from generalized EoS
F. Contreras, N. Cruz, G. Palma
We present an exact analytical bouncing solution for a closed universe filled with only one exotic fluid with negative pressure, obeying a Generalized Equations of State (GEoS) of…

Generalized equations of state and regular universes
Felipe Contreras, Norman Cruz, Esteban González
We found non singular solutions for universes filled with a fluid which obey a Generalized Equation of State of the form . An emergent universe is obtained if …
