Infinitely many solutions of Einstein cosmology in ``slow-roll''
Abstract
We show that the ``slow-roll'' approximated Einstein equations involving two coupled scalar fields, one which serves as the inflation field and another which has a decaying potential, have infinitely many solutions. We give exact analytic forms of two such solutions. We conjecture that the infinitely many solutions are ``equivalent''.
