Bianchi Type - II, VIII and IX Dark Energy Cosmological Models in Saez-Ballester Theory of Gravitation

Spatially homogeneous Bianchi type - II, VIII & IX dark energy anisotropic as well as isotropic cosmological models with variable equation of state (EoS) parameter are presented in a scalar tensor theory of gravitation proposed by Saez and Ballester (1986) To get a determinate solution of the field equations we take the help of a special law of variation for Hubble's parameter presented by Bermann (1983) which yield cosmological models with negative constant deceleration parameter. Some important features of the models, thus obtained, have been discussed.
