Abstract

We consider the evolution of homogeneous cosmologies toward the future in a dynamical systems formulation.
Using a variational equation approach, we show that there is a short period in which transient
solutions between the end of a Mixmaster era and a subsequent Friedmannian state exist. Implications of
the generic inhomogeneous evolution toward the future, the recollapse problem, the horizon problem, and
the initial conditions required for inflation are briefly discussed.
