Cosmological solution in Brans-Dicke theory involving particle creation in relativistic viscous fluid universe

Abstract

The problem of the particle creation in the viscous fluid universe in the Brans-Dicke field theory is studied in this paper. The solutions obtained are investigated with respect to the Dirac's hypothesis along with the discussion of the gravitational parameters as well as the variable gravitational constants. By adopting a particular method of integration, exact solutions are obtained corresponding to the three values of curvature index and physical interpretations are presented.
