摘要：

In this paper,we obtain some sharp inequalities between the Ricci curvature and the squared mean curvature for bi-slant and semi-slant submanifolds in Kenmotsu space forms.Estimates of the scalar curvature and the k-Ricci curvature, in terms of the squared mean curvature,are also proved respectively.
