Almost Kenmotsu manifolds with constant Reeb or Ф-sectional curvatures
Almost Kenmotsu manifolds with constant Reeb or Ф-sectional curvatures
In this paper, we prove that an almost Kenmotsu manifold M has constant Reeb sectional curvatures if and only if M has conformal Reeb foliation. Onan almost Kenmotsu h-a-manifold of dimension three having constant ?-sectional curvature, the Reeb vector field is an eigenvector field of the Ricci operator if and …
