Some curvature tensors on almost α-Cosymplectic three-manifolds

This thesis consists of five chapters. The first chapter is devoted to the introduction section and provide a generel knowledge of literature. In the second chapter, the necessary basic concepts are introduced. In the third chapter, the structure of almost α-cosymplectic manifold is considered and curvature properties of this structure are examined. In the fourth chapter, some general results for α-Kenmotsu manifold connected to the semi symmetric conditions are given. In the fifth chapter, semi symmetric almost α-cosymplectic three manifold is addressed in detail and some results are obtained on almost α-cosymplectic three manifold
