No stable dissipative phantom scenario in the framework of a complete cosmological dynamics
Norman Cruz, Samuel Lepe, Yoelsy Leyva +2
We investigate the phase space dynamics of a bulk viscosity model in the Eckart approach for a spatially flat Friedmann-Robertson-Walker universe. We have included two barotropic f…
