摘要：
Some properties of quasi-T-flat, xi-T-flat and phi-T-flat K-contact and Sasakian manifolds are obtained. We give the necessary and sufficient condition for the K-contact manifold to be xi-T-flat under some algebraic condition. Among others, it is proved that a compact phi-T-flat K-contact manifold with regular contact vector field, under an algebraic condition, is a principal S-1-bundle over an almost Kaehler space of constant holomorphic sectional curvature.
