摘要：We consider some conditions on conharmonic curvature tensor ˜ C, which has many applications in physics and mathematics. We prove that every ϕ-conharmonically symmetric n-dimensional (n > 3), Sasakain manifold is an Einstein manifold. Also we prove that a three-dimensional Sasakian manifold is locally ϕ-conharmonically symmetric if and only if it is locally ϕ- symmet- ric. Finally we give two examples of a three-dimensional ϕ-conharmonically symmetric Sasakian manifold.
