Semi-invariant submanifolds of K-manifolds

, 2012
We are concerned with $\mathcal K$-manifolds which are a natural generalization of metric quasi-Sasakian ma\-ni\-folds. They are Riemannian manifolds with a compatible $f$-stru\-ctu\-re which admits a parallelizable kernel, have closed Sasaki 2 ...

Semi-invariant lightlike submanifolds of a semi-Riemannian product manifold

, 2007
In this paper, we introduce a new class of lightlike submanifolds, namely, semi-invariant lightlike submanifolds of a semi-Riemannian product manifold. We investigate totally umbilical, curvature invariant lightlike submanifolds in real space forms M-1(c(

The index and certain stability of minimal anti invariant submanifolds in Sasakian and Kähler Manifolds

Tsukuba Journal of Mathematics, 2001
The author derives a formula for the index form associated to the volume of a compact orientable minimal submanifold \(P\) of a Sasakian manifold \(M\), where the submanifold \(P\) is assumed to be orthogonal to the structure vector field of \(M\). Using this formula, stability questions are investigated.

Some solitons on anti-invariant submanifold of LP-Kenmotsu manifold admitting Zamkovoy connection

Journal of Hyperstructures
In this paper we prove some curvature properties of anti-invariant submanifold of Lorentzian para-Kenmotsu manifold (briefly, LP-Kenmotsu manifolds) with respect to Zamkovoy connection (∇∗). Next, we study Einstein soliton on anti-invariant submanifold of LP-Kenmotsu manifold with respect to Zamkovoy connection.

On invariant submanifolds of almost ?-kenmotsu manifolds [PDF]

, 2016
The purpose of this paper is to study invariant submanifolds of almost ?- Kenmotsu manifolds. In particular, we prove that these kinds of submanifolds are totally geodesic under a certain condition.

Invariant and screen semi-invariant lightlike submanifolds of a metallic semi-Riemannian manifold with a quarter symmetric non-metric connection

, 2023
This research work introduces the structure of invariant and screen semi-invariant lightlike submanifolds of a metallic semi-Riemannian manifold with a quarter symmetric non-metric connection, elaborated with examples. It delves into the characterization

Invariant, anti invariant and slant submanifolds of locally poly-norden manifolds

Boletim da Sociedade Paranaense de Matemática
In this paper, we study locally almost 3-poly-Norden manifolds and prove several properties of the curvature tensor and Ricci tensor of these manifolds. We investigate invariant, anti-invariant and slant submanifolds of almost 3-poly-Norden manifolds from various views. We characterize these submanifolds and give non-trivial examples.

Submanifolds of generalized Sasakian space forms [PDF]

, 2009
In the present paper submanifolds of generalized Sasakian-spaceforms are studied. We focus on almost semi-invariant submanifolds, these generalize invariant, anti-invariant, and slant submanifolds.
