Study of certain structures and connections with almost para-contact metreic manifolds

In this paper, we study a new type of semi-symmetric metric connections with almost para-contact Riemannian manifolds in the such type of bundle. We established the new relations between curvature tensor and Nijenhuis tensor in a Riemannian connection and also consider the submanifolds of a Riemannian with respect to the semi-symmetric metric connection in the structure
