Phys. Rev. D 62, 084029 (2000) [10 pages]Assisted inflation in Friedmann-Robertson-Walker and Bianchi spacetimesReceived 18 April 2000; published 26 September 2000 We use exact general solutions for the spatially flat FRW and the anisotropic Bianchi type I cosmologies to show that generically uncoupled scalar fields cooperate to make inflation more probable, while the presence of several interacting fields hinders the occurrence of the phenomenon, in accordance with previous results based on particular power-law solutions. Similar conclusions are reached in the case of Bianchi type VI0 spacetimes, for power-law solutions which are proved to be attractors. © 2000 The American Physical Society URL:
