Scientific paper

It is well known that an initial kinetic term does not prevent the onset of ``chaotic'' inflation. In this paper we extend this investigation to ``new'' inflation scenarios. We find that in the case of ``new'' inflation as in the case of ``chaotic'' inflation there exists a curve that attracts most of the solutions. However, unlike the ``chaotic'' inflation case where the attractor is the inflationary solution, in the ``new'' inflation case the attractor is the slow rolling solution and only a small part of it corresponds to inflation. So unlike the ``chaotic'' case where the inflationary stage is generic, in the ``new'' inflation case only very specific initial conditions lead to inflation.
