On the Stability of Jordan-Brans-Dicke Static Universe
Sergio del Campo, Ramon Herrera, Pedro Labrana
In this work we study the stability of the Jordan-Brans-Dicke (JBD) static universe. This is motivated by the possibility that the universe might have started out in an asymptotica…

Evolving Lorentzian wormholes supported by phantom matter and cosmological constant
Mauricio Cataldo, Sergio del Campo, Paul Minning +1
In this paper we study the possibility of sustaining an evolving wormhole via exotic matter made of phantom energy in the presence of a cosmological constant. We derive analytical…

Evolving Lorentzian wormholes supported by phantom matter with constant state parameters
Mauricio Cataldo, Pedro Labrana, Sergio del Campo +2
In this paper we study the possibility of sustaining an evolving wormhole via exotic matter made out of phantom energy. We show that this exotic source can support the existence of…
