We use exact general solutions for
the spatially flat FRW and the
anisotropic Bianchi-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-VIo spacetimes, for power-law
solutions which are proved to be
attractors.
