By allowing the equation of state for matter to be of a decompressive nature we study the effect on entropy generation in a ten-dimensional cosmological model. We study the three cases when bulk viscosity is constant, depends on the energy density, and lastly, on the square of the curvature.
Solutions to flat space Friedmann Robertson Walker cosmologies in Brans Dicke theory with a cosmological constant are investigated. The matter is modeled as a #-law perfect fluid. The field equations are reduced from fourth order to second order through a change of variables, and the resulting two-d
