Ricci curvature of submanifolds in locally conformal almost cosymplectic manifolds

2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/57099We obtain certain inequalities involving several intrinsic invariants namely scalar curvature, Ricci curvature and $k$-Ricci curvature, and main extrinsic invariant namely squared mean curvature for submanifolds in a locally conformal almost cosymplectic manifold with pointwise constant $% ϕ$-sectional curvature. Applying these inequalities we obtain several inequalities for slant, invariant, anti-invariant and {\em CR}-submanifolds. The equality cases are also discussed.Latex 14 pagesMathematical Physics53C40 (53C15, 53C25)Ricci curvature of submanifolds in locally conformal almost cosymplectic manifoldstext
