Khan, V.A. Khan and Siraj Uddin, Balkan J. Geom. Appl. 13 (2008), 55{65]. The nearly co- symplectic structure generalizes the cosymplectic one. Therefore the nearly Kaehler structure generalizes the Kaehler structure in almost Hermitian set- ting. It is interesting that the warped product semi-slant submanifolds exist in the nearly cosymplectic case while in the cosymplectic case they do not. In the beginning, we prove some preparatory results and finally we obtain an inequality such as {norm of matrix} h {norm of matrix} 2 ? 4q csc2 ?{1+ 1/9 cos2 ?}{norm of matrix} ?r ln f {norm of matrix} 2 in terms of intrinsic and extrinsic invariants. The equality case is also considered.eninfo:eu-repo/semantics/closedAccessNearly Cosymplectic ManifoldSemi-Slant SubmanifoldSlant SubmanifoldWarped ProductsArticle55155692-s2.0-84902953317Q3
