SOME STRING COSMOLOGICAL MODELS IN BIANCHI TYPE-I SPACE-TIME

We obtain some cosmological models that are exact solutions of Einstei n's field equations. The metric utilized is Marder's metric which is B ianchi Type I and the curvature source is a cloud of strings which are one dimensional objects. Bianchi type cosmological models play an imp ortant role in the study of the universe on a scale which anisotropy i s not ignored. In this paper we have investigated the effect of cosmic strings on the cosmic microwave background anisotropy. Various physic al and geometrical properties of the model are also discussed. The sol utions have reported that the cosmic microwave background anisotropy m ay due to the cosmic strings.
