Geometric inequalities for CR-warped products of locally conformal almost cosymplectic manifolds

Abstract

In this paper, we establish some inequalities for the squared norm of the second fundamental form and warping function of warped product submanifolds in locally conformal almost cosymplectic manifolds with pointwise ϕ-sectional curvature. The equality cases are also considered. Moreover,weproveatrivialityresultforCR-warpedproductbyusingtheintegrationtheory on compact orientable manifold without boundary.
