Summary
We give exact solutions of the «slow-roll» approximated Einstein equations for the inflationa(t)=a 0(1+αt/p)p in a model (Phys. Lett. A,172, 404 (1993)) withtwo coupled scalar fields. These solutions should be of considerable interest for analyses of the implications of the large-scale anisotropy recently observed by COBE in the cosmic microwave background radiation.
