Exact inflationary solutions
Gabriella Piccinelli, Tonatiuh Matos, Merced Montesinos
Abstract
We present a new class of exact inflationary solutions for the evolution of a universe with spatial curvature, filled with a perfect fluid, a scalar field with potential V(ϕ)=λ(ϕ2δ2)2 and a cosmological constant Λ. With the V+(ϕ) potential and a negative cosmological constant, the scale factor experiments a graceful exit. We give a brief discussion about the physical meaning of the solutions.
