Some type of semisymmetry on two classes of almost Kenmotsu manifolds

Abstract The object of the present paper is to study some types semisymmetry conditions on two classes almost Kenmotsu manifolds. It shown that a ( k, µ )-almost manifold satisfying curvature condition Q · R = 0 locally isometric hyperbolic space ℍ 2 n +1 (−1). Also in manifolds following conditions: (1) local symmetry (∇ 0), (2) (3) S, ) 0, (4) ), (5) (−1) are equivalent. Further, it proved )′ -almost (−4) × ℝ and any one or either an Einstein . Finally, illustrative example presented.
