Initial conditions for new inflation
Description
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. (orig.)
