On P-Sasakian Manifolds Satisfying Certain Conditions on the Concircular Curvature Tensor
P-Sasakian manifold concircular curvature tensor Weyl conformal curvature tensor
2010/2/26
We classify P-Sasakian manifolds, which satisfy the conditions Z(x ,X) · Z = 0, Z(x ,X) · R = 0, R(x ,X) · Z = 0, Z(x ,X) · S = 0 and Z(x ,X) · C = 0.
