Minimal Reeb vector fields on almost Kenmotsu manifolds
A necessary and sufficient condition for the Reeb vector field of a three dimensional non-Kenmotsu almost Kenmotsu manifold to be minimal is obtained. Using this result, we obtain some classifications of some types of -almost Kenmotsu manifolds. Also, we give some characterizations of the minimality of the Reeb vector fields of -almost Kenmotsu manifolds. In addition, we prove that the Reeb vector field of an almost Kenmotsu manifold with conformal Reeb foliation is minimal.
