Scientific paper

Nonflat Bianchi type-II vacuum- and stiff-fluid models in the presence of zero-mass scalar fields are obtained. The study starts with Einstein field equations, then the energy-momentum tensor for perfect-fluid distribution is considered, and the energy conservation equation is derived. The resulting field equations are then reduced to the stiff-fluid case, and the Bianchi type-II stiff-fluid model in the presence of zero-mass scalar fields is obtained and then reduced to the vacuum Bianchi type-II model in the presence of zero-mass scalar fields.
