摘要：
We investigate the isotropization of the Bianchi type-IX models with an exponential potential of the form V(phi) = Lambda e(k phi). If the parameter k<J root 2 then there exists a set of ever-expanding anisotropic Bianchi type-IX models that isotropize and inflate towards an expanding power-law inflationary solution. If k> root 2 then initially expanding Bianchi type-M models do not isotropize towards an ever-expanding isotropic model. [S0556-2821(99)05910-X].
