Abstract: In the present paper, we obtain sharp inequalities between the Ricci curvature and the squared mean curvature for slant,semi-slant and bi-slant submanifolds in Sasakian space forms. Also, estimates of the scalar curvature and the $k$-Ricci curvature respectively, in terms of the squared mean curvature, are proved.
Keywords: bi-slant submanifold, Ricci curvature, mean curvature, Sasakian space form, semi-slant submanifold, slant submanifold.
