Abstract
We obtain a general exact solution of the Einstein field equations for the anisotropic Bianchi type I universes filled with an exponential-p otential scalar field and study their dynamics. It is shown, in agreem ent with previous studies, that for a wide range of initial conditions the late-time behavior of the models is that of a power-law inflating Friedmann-Robertson-Walker (FRW) universe. This property does not hol d, in contrast, when some degree of inhomogeneity is introduced, as di scussed in our following paper.
