Resumen de On three-dimensional trans-Sasakian manifolds
The object of the present paper is to study 3-dimensional trans-Sasakian manifolds which are locally Á-symmetric and have ´-parallel Ricci tensor. Also 3-dimensional trans- Sasakian manifolds of constant curvature have been considered. An example of a three- dimensional locally Á-symmetric trans-Sasakian manifold is given.
