Phantom cosmology with a decaying cosmological function Λ(t) induced from five-dimensional (5D) geometric vacuum

Abstract

Introducing a variable cosmological function L (t) in a geometrical manner from a 5D Riemann-flat metric, we investigate the possibility of having a geometric criterion to choose a suitable cosmological function L (t) for every 4D dynamical hypersurface capable of generating phantom cosmologies.
