The paper is devoted to the study of cosmological models with time-varying cosmological term (Λ) in the presence of creation field in the framework of Bianchi type III space-time. To obtain deterministic model of the universe, we have assumed Λ∝1

A solution of Einstein’s field equations that admits barotropic fluid distribution and a negative-energy massless scalar creation field as a source in the presence of bulk viscosity and time-dependent vacuum energy density (Λ) is investigated. It

A model formed by creation field and variable cosmological constant with perfect fluid is investigated. Bianchi type III space time is used as a source of investigation. To get deterministic model, a relation between shear (σ) and expansion (θ) is
