Bianchi Type-III Cosmic Strings and Domain Walls Cosmological Models in Self-creation Cosmology

Shivdas D Katore, A. Y. Shaikh, M. M. Sancheti, N. K. Sarkate


Bianchi type-III space-time is considered in the presence of cosmic string source and thick domain walls in Barber’s (Gen. Relativ. Gravit. 14:117, 1982) Second self-creation theory of gravitation. With the help of special law of gravitation for Hubble’s parameter proposed by Bermann (Nuovo Cimento 74 B: 182, 1983) cosmological models with negative constant deceleration parameter are obtained. It is interesting to note the cosmological models, obtained in both the cases, are identical. Some physical and kinematical properties of the models are discussed.
