Axially symmetric string cosmological models in Brans-Dicke theory of gravitation

Axially symmetric string cosmological models are obtained in a scalar- tensor theory of gravitation proposed by Brans and Dicke (Phys. Rev. 124:925, 1961 ). Some physical and geometrical properties of the models are also discussed. The models are anisotropic and free from singularities.
