Abstract:
We have studied the Hoyle – Narlikar C- field cosmology for LRS Bianchi type ii with time varying cosmological constant Ʌ(t) for barotropic perfect fluid distribution. To get deterministic solution we assume that Λ=1/R^2 as considered by Chen and Wu, where R is a scale factor and A = B where A and B are metric potentials. The conservation equation T_(i;j)^j=0 and T_j^i=T_i(m)^j+ T_i(c)^j, T_i(m)^jbeing energy-momentum tensor for matter and T_i(c)^jis the energy momentum tensor for C-field. We find that creation field (C) increase with time and Λ~1/t^2which matches with the result obtained by Hoyle Narlikar theory. Above we have discussed special cases of model (28) like dust filled universe (γ= 0), stiff fluid universe (γ = 1) and radiation dominated universe (γ = 1/3). The physical and geometrical aspects for this model are also studied.
