C-field Cosmological Model for Dust Distribution with Varying Λ in FRW Space-time

Abstract

A cosmological model in creation field cosmology with varying L in the framework of FRW space-time is investigated. Following Hoyle and Narlikar (1964), we have assumed that universe is filled with dust distribution. To get the deterministic model, we have assumed that Λ=1/R² where R is the scale factor. We find that creation field increases with time and matter density is constant which is maintained due to continuous creation of matter. Λ~1/t² and particle horizon does not exist. The model represents accelerating universe which matches with the result obtained by Riess et al. (1998) and Perlmutter et al. (1999).
