Abstract
From four-dimensional N = 4 matter-coupled gauged supergravity, we study smooth time-dependent cosmological solutions interpolating between a dS 2 × Σ2 spacetime, with Σ2 = S 2 and H 2, in the infinite past and a dS 4 spacetime in the infinite future. The solutions were obtained by solving the second-order equations of motion from all the ten gauged theories known to admit dS 4 solutions, of which there are two types. Type I dS gauged theories can admit both dS solutions as well as supersymmetric AdS solutions while type II dS gauged theories only admit dS solutions. We also study the extent to which the first-order equations that solve the aforementioned second-order field equations fail to admit the dS 4 vacua and their associated cosmological solutions.
