Starobinsky-like inflation and running vacuum in the context of Supergravity
TL;DR: In this paper, the primeval inflationary phase of the early universe was described within a quantum field theoretical framework that can be viewed as the effective action of vacuum decay in the early times.
Phase space analysis of the accelerating multifluid Universe
TL;DR: In this paper, the phase space of a Friedmann-Robertson-Walker universe with various cosmological fluids that may or may not interact is studied, and the physical significance of the resulting fixed points is analyzed.
