Some relationships between intrinsic and extrinsic invariants of submanifolds in generalized $S$-space-forms
We establish some inequalities of Chen’s type between certain intrinsic
invariants (involving sectional, Ricci and scalar curvatures) and the
squared mean curvature of submanifolds tangent to the structure vector
fields of a generalized $S$-space-form and we discuss the equality cases
of them. We apply the obtained results to slant submanifolds.
