Exact inflationary solutions

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 $V_{\pm }(\varphi )=\lambda ({\varphi }^2\pm {\delta }^2{)}^2$ and a cosmological constant $\Lambda$. With the $V_{+}(\varphi )$ 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.
