Abstract:
We construct perfect fluid metrics with two symmetries by means of a recently developed geometrical method 1]. The Einstein equations are reduced to a single equation for a conformal factor. Under additional assumptions we obtain new cosmological solutions of Bianchi type II, VI0 and VII0. The solutions depend on an arbitrary function of time, which can be specified in order to satisfy an equation of state.
