Phantom cosmology with a decaying cosmological function $\Lambda (t)$ induced from five-dimensional (5D) geometrical vacuum

Abstract

Introducing a variable cosmological function $\Lambda (t)$ 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 $\Lambda (t)$ for every 4D dynamical hypersurface capable of generate phantom cosmologies.
