چکیده
|
We classify the paracontact riemannian manifolds that their riemannian curvature satisfies in the certain condition and we show that this classification holds for the special cases semi-symmetric and locally symmetric spaces. finally we study paracontact riemannian manifolds satisfying r(x, ξ)·s = 0, where s is the ricci tensor.
