Quarter symmetric connections on S-manifolds

In this thesis, quarter symmetric non-metric connection and quarter symmetric metric connection are defined on S-manifolds. In addition, some theorems and examples are given about these connections on S-manifolds. Moreover, the curvatures 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 Word : S-manifolds, Çeyrek symmetric connection
