Tachyonic Universes in Patch Cosmologies with $\Omega>1$

General Relativity and Quantum Cosmology 2015-05-13 v2

Abstract

In this article we study closed inflationary universe models by means of a tachyonic field. We described a general treatment for created a universe with Ω>1\Omega>1 in patch cosmology, which is able to represent General Relativity, Gauss-Bonnet or Randall-Sundrum patches. We use recent data from astronomical observations to constrain the parameters appearing in our model.
