Exact inflationary cosmologies with exit

R Maartens, D. R. Taylor, N Roussos

Research output: Contribution to journalArticlepeer-review


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 tit<te, and then directs the expansion smoothly towards radiationlike evolution for t≥te.
