Three-Dimensional Semi-Symmetric Almost α-Cosymplectic Manifolds

Abstract

The main objective of this paper is to study semi-symmetric almost -cosymplectic three-manifolds. We present basic formulas for almost -cosymplectic manifolds. Using curvature properties, we obtain some necessary and sufficient conditions on semi-symmetric almost -cosymplectic three-manifolds. We obtain the main results under an additional condition. The paper concludes with two illustrative examples.
