Query: Chaotic exit to inflation: pre-inflationary Friedmann-Robertson-Walker
  universes   We show that homogeneous and isotropic cosmological models with radiation and
scalar field have, in general, two possible chaotic exits to inflation. These
models may describe the early stages of inflation. The central point of our
analysis is based on the possible existence of one or two saddle-centers points
in the phase space of the models.
