On manifolds with the Schouten-Van Kampen connection

This thesis consists of four chapters. In the introduction chapter of the thesis, the emergence, geometric meanings and related studies of the problems to be discussed in the following chapters are introduced. In the second chapter, basic concepts, definitions and theorems which will be used in the other parts of the thesis are given. In the third chapter, firstly, 3-dimensional f-Kenmotsu manifolds with the Schouten-van Kampen (shortly S.v.K.) connection are examined. Then, characterizations related to the fact that such a manifold is semisymmetric, Ricci semisymmetric, projectively semisymmetric and conharmonically semisymmetric are presented, respectively. Finally, in the fourth chapter, 3-dimensional Quasi-Sasakian (shortly q.S.) manifolds with the S.v.K. connection are examined. Firstly, the S.v.K. connection equation is given on such a manifold and its curvature tensor, Ricci tensor, Ricci operator and scalar curvature are defined. Then, characterizations related to projectively flat, concharmonically flat, locally φ-symmetric and Ricci tensor being η-parallel states of such manifolds are presented. Then, Da-homothetic deformation was investigated on 3-dimensional q.S. manifolds with the S.v.K. connection. Then,characterizations related to semisymmetric, projectively flat, concircularly flat, locally φ-symmetric and Ricci tensor being η-parallel states of such manifolds are presented. At the end of the chapter, two examples are given to 3-dimensional q.S. manifolds with the S.v.K. connection.
