Marcelo Samuel Berman
We find a solution for exponential inflation in Brans-Dicke cosmology endowed with a cosmological term, which includes time-varying shear and vorticity. We find that the scalar fie…

Natural Entropy Production in an Inflationary Model for a Polarized Vacuum
Marcelo Samuel Berman, Murari M. Som
Though entropy production is forbidden in standard FRW Cosmology, Berman and Som presented a simple inflationary model where entropy production by bulk viscosity, during standard i…
