摘要:Let M be a three-dimensional trans-Sasakian manifold of type (alpha, beta). In this paper, we obtain that the Ricci operator of M is invariant along Reeb flow if and only if M is an alpha-Sasakian manifold, cosymplectic manifold or a space of constant sectional curvature. Applying this, we give a new characterization of proper trans-Sasakian 3-manifolds.
