Invariants of submanifolds in Euclidean space
1997The topology of the set of singular support hyperplanes and hyperspheres to a smooth submanifold in Euclidean space is studied. As a corollary, some relations between differential-geometric characteristics of a manifold are obtained. In particular, if a simple closed embedded generic curve in a plane has C global vertices (where the curvature circles ...

ON INVARIANT SUBMANIFOLDS OF ALMOST ?-KENMOTSU MANIFOLDS
The purpose of this paper is to study invariant submanifolds of almost alpha-Kenmotsu manifolds. In particular, we prove that these kinds of submanifolds are totally geodesic under a certain condition. Finally, an example of threedimensional almost alpha-Kenmotsu manifold is given.openaire +2 more sources
Invariant submanifolds in a contact Riemannian manifold
1985Let \(\bar M\) be a contact Riemannian manifold with structure tensors (\(\phi\),\(\xi\),\(\eta\),g), i.e. \(\eta\) is a contact form, meaning that \(\eta \Lambda (d\eta)^ n\neq 0\), \(\xi\) its characteristic vector field, g a Riemannian metric and \(\phi\) a tensor field of type (1,1) such that \(\phi^ 2=-I+\eta \otimes \xi\), \(\eta (X)=g(\xi,X)\), \
