On the geometry of some curvatures of paracontact metric manifolds

In this thesis, we study the effects of the concircular curvature tensor of a normal paracontact metric manifold on Riemann curvature tensor, Projective curvature tensor, concircular curvature tensor, Ricci tensor and quasi-conformal curvature tensor. According to the results obtained, the theorem and results characterizing a normal paracontact metric manifold are given.
