Phantom cosmology with a decaying cosmological function $Λ(t)$ induced from five-dimensional (5D) geometrical vacuum
Introducing a variable cosmological function $Λ(t)$ in a geometrical manner from a 5D Riemann-flat metric, we investigate the possibility of having a geometrical criterion to choose a suitable cosmological function $Λ(t)$ for every 4D dynamical hypersurface capable of generate phantom cosmologies.
