Projective Curvature Tensorin 3-dimensional Connected Trans-Sasakian Manifolds
The object of the present paper is to study -projectively flat and -projectively flat 3-dimensional connected trans-Sasakian manifolds. Also we study the geometric properties of connected trans-Sasakian manifolds when it is projectively semi-symmetric. Finally, we give some examples of a 3-dimensional trans-Sasakian manifold which verifies our result.
