ABSTRACT
Bianchi type-IX cosmological models with variable equation of state (EoS) parameter have been investigated in general relativity when universe is filled with dark energy. The field equations have been solved by considering (i) q=B (variable); (ii)
, where k and m are constants; (iii) 
, where k is constant and R is average scale factor; (iv) 
which gives 
. This renders early decelerating and late time accelerating cosmological models. The physical and geometrical properties of the models are also discussed.
