On Alpha Kenmotsu Pseudo Metric Manifolds

The aim of this paper is to investigate some curvature properties on alpha Kenmotsu pseudo metric manifolds. In particular, the tensor conditions such as locally symmetry, globally ?-symmetry and locally ?-symmetry under some additional conditions on such manifolds are considered. Also, the necessary and sufficient conditions for ?-Einstein and Einstein manifolds are studied. Furthermore, some results are related to ?-sectional and ?-sectional curvatures on alpha Kenmotsu pseudo metric manifolds are given. Finally, the paper is concluded with an illustrative example for alpha Kenmotsu pseudo metric manifolds.
