On Certain Concircular Flatness Conditions on Almost Cosymplectic Manifolds with Schouten-Van Kampen Connection

The objective of this paper is to study a Schouten-Van Kampen connection ∇ on almost cosymplectic manifolds. We establish geometric properties of almost cosymplectic manifolds with respect to a ∇ with flatness conditions to be ϕ- concircular and ξ-concircular, pseudo-concircular curvature tensor.
