摘要
Following the gravitational theory proposed by Bermann, homogeneous and isotropic cosmological models with variable cosmological constant and gravitational constant have been constructed which satisfy the present day observational data and the initial condition as proposed by Sivaram et al.,(23) with additional requirement that 8 pi G rho = alpha Lambda c(2).
