Sergio del Campo, Ramon Herrera, Pedro Labrana (PUCV)
TL;DR
This paper explores an emergent universe scenario within Jordan-Brans-Dicke theory, demonstrating a stable static past and transition to inflation, with parameter constraints established.
Contribution
It introduces a novel emergent universe model in Jordan-Brans-Dicke theory with stability analysis and parameter constraints.
Findings
Stable past eternal static solution identified
Transition to inflationary phase demonstrated
Parameter constraints for the model established
Abstract
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 eventually enters a phase where the stability of this solution is broken leading to an inflationary period. We also establish constraints for the different parameters appearing in our model.
