Invariant submanifolds in a Riemannian product manifold

TRU Mathematics, 1986
Let M be a Riemannian submanifold immersed in a Riemannian product manifold N. Let F be the product tensor field of N. The submanifold M is said to be invariant if the tangent space \(T_ x(M)\) at any point x of M is invariant under the action of the tensor field F. In the present paper, the author studies such invariant submanifolds.

An invariant of a submanifold transversal to a distribution

Russian Mathematical Surveys, 1988
In this paper the author gets an extension to the case of arbitrary dimensions of the isotopy invariant obtained by \textit{D. D. Bennequin} in the case of the curves transversal to a contact structure in a 3- dimensional manifold [Astérisque 107/108, 87-161 (1983; Zbl 0573.58022)]. Let \(\xi^{2n}\) be a distribution of codimension one in the \((2n+1)\)

Invariants of submanifolds in Euclidean space

1997
The 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 \(S\)-manifolds

2019
Summary: We consider invariant, pseudo-parallel and Ricci generalized pseudo-parallel submanifolds of \(\mathcal{S} \)-manifolds. We show that the submanifolds are totally geodesic under certain conditions. Also we study an invariant submanifold of \(\mathcal{S} \)-manifold satisfying \(Q(\sigma,R)=0\) and \(Q(S,\sigma)=0\), where \(S, R\) and \(\sigma\
