Chen's inequalities for biwarped product submanifolds in complex space forms

摘要

In the present paper, we investigate an optimal inequality for the squared norm of the mean curvature vector for the Biwarped product submanifolds isometrically immersed into complex space forms, in the ex pressions of constant sectional curvature c, Laplacian of the warping func tions and slant function. The equality case is likewise discussed. Some special cases are also discussed.
