- Abstract
Bianchi Type III bulk viscous dust filled cosmological models in Lyra geometry are investigated. To get the deterministic model of the universe, we have assumed two conditions: (i) ζ θ=constant; and (ii) shear ( σ) is proportional to the expansion ( θ). This condition leads to B= C n where ζ the coefficient of bulk viscosity, θ the expansion in the model; B and C are metric potentials and n a constant. The physical and geometrical aspects of the model and singularities in the model are also discussed.
