Canonical Scalar Field Inflation with a Woods-Saxon Potential
V. K. Oikonomou, N. Th. Chatzarakis
This paper focuses on the realization of an inflationary model from a canonical scalar field theory with a Woods-Saxon potential, in the slow-roll approximation. Our analysis indic…

Autonomous Dynamical System of Einstein-Gauss-Bonnet Cosmologies
N. Chatzarakis, V. K. Oikonomou
In this paper, we study the phase space of cosmological models in the context of Einstein-Gauss-Bonnet theory. More specifically, we consider a generalized dynamical system that en…

Effects of Spatial Curvature on the Gravity Phase Space: no Inflationary Attractor?
S. D Odintsov, V. K. Oikonomou
In this paper we study the effects of spatial curvature of the metric on the phase space of vacuum gravity. Particularly, we appropriately choose the variables of the dynami…
