Abstract

We find exact inflationary solutions with exit, including exact forms of the potential, by specifying the rate of expansion and using the number of e-foldings as the effective dynamical variable. These include solutions in which the potential drives nearly exponential or power-law inflation for t_i≤t<t_e, and then directs the expansion smoothly towards radiationlike evolution for t≥t_e.
