| Abstract: | An axially symmetric Bianchi type-I space-time is considered in the presence of perfect fluid source in the scale-covariant
theory of gravitation formulated by Canuto et al. 1977a, Phys. Rev. Lett. 39, 429]. With the help of special law of variation for Hubble’s parameter proposed by Bermann 1983, Nuovo Cimento 74B, 182] a cosmological model with a negative constant declaration parameter is obtained in this theory. Some physical properties
of the model are also discussed. |
