A cosmological model with negative constant deceleration parameter in a general scalar-tensor theory of gravitation. (English) Zbl 1252.83120
Summary: A spatially homogeneous and anisotropic LRS Bianchi type-I metric is considered in the framework of Nordtvedt-Barker’s general scalar-tensor theory of gravitation when the source for the energy momentum tensor is a perfect fluid. With the help of a special law of variation for Hubble’s parameter proposed by M. S. Bermann [“A special law of variation for Hubble’s parameter”, Nuovo Cimento, XI. Ser. B 74, 182–186 (1983; doi:10.1007/BF02721676)], a cosmological model with negative constant deceleration parameter is obtained. Some physical and kinematical properties of the model are also discussed.
