Semi symmetric connections on s-manifolds

In this thesis, semi symmetric non-metric connection and semi symmetric metric connection are defined on S-manifolds. In addition some theorems and examples are given about these connections on S-manifolds. Moreover, the curvature and Ricci curvature of such connections are obtain, and the conditions of semi-symmetry, Ricci semi symmetric, Ricci projectif semi symmetry and projectif semi symmetry are investigated.Key Words : S-manifolds, Semi symmetric connection
