Emergent universe in a Jordan-Brans-Dicke theory
Sergio del Campo, Ramon Herrera, Pedro Labrana
In this paper we study emergent universe model in the context of a self interacting Jordan-Brans-Dicke theory. The model presents a stable past eternal static solution which eventu…
Tachyonic open inflationary universes
Leonardo Balart, Sergio del Campo, Ramon Herrera +2
We study one-field open inflationary models in a universe dominated by tachyon matter. In these scenarios, we determine and characterize the existence of the Coleman-De Lucia (CDL)…
Closed inflationary universe with tachyonic field
Leonardo Balart, Sergio del Campo, Ramon Herrera +1
In this article we study closed inflationary universe models by using a tachyonic field theory. We determine and characterize the existence of an universe with , and which de…
