Sažetak
Bianchi type-I stiff-fluid tilted cosmological model with bulk viscosity is investigated. To get the deterministic model of the universe, we have assumed that the universe is filled with a stiff fluid, a condition A = (BC) n between the metric potentials A, B, C and ζθ =constant, where ζ is the coefficient of bulk viscosity, θ the expansion and n is a constant. The physical and geometrical aspects of the model in the presence and absence of bulk viscosity are discussed.
