Global dynamics of two models for Quintom Friedman-Lemaître-Robertson-Walker Universes
Genly Leon, Alan Coley, Andronikos Paliathanasis +2
We comprehensively analyze the dynamics for the gravitational field equations for the Chiral-Quintom theory in a Friedman-Lemaître-Robertson-Walker cosmology with an additional mat…

Scalar Field cosmology from a Modified Poisson Algebra
Genly Leon, Alfredo D. Millano, Andronikos Paliathanasis
We investigate the phase space of a scalar field theory obtained by minisuperspace deformation. We consider quintessence or phantom scalar fields in the action which arise from min…
