Rank and k-nullity of contact manifolds
We prove that the dimension of the 1-nullity distributionN(1) on a closed Sasakianmanifold M of rank l is at least equal to 2l−1 provided thatM has an isolated closed characteristic. The result is then used to provide some examples ofK-contact manifolds which are not Sasakian. On a closed, 2n+ 1-dimensional Sasakian manifold of positive bisectional curvature, we show that either the dimension o...
متن کاملOn 3-dimensional Almost Kenmotsu Manifolds Admitting Certain Nullity Distribution
The aim of this paper is to characterize 3-dimensional almost Kenmotsu manifolds with ξ belonging to the (k, μ)′-nullity distribution and h′ 6= 0 satisfying certain geometric conditions. Finally, we give an example to verify some results.
متن کاملSemi-slant Pseudo-riemannian Submersions from Indefinite Almost Contact 3-structure Manifolds onto Pseudo-riemannian Manifolds
In this paper, we introduce the notion of a semi-slant pseudoRiemannian submersion from an indefinite almost contact 3-structure manifold onto a pseudo-Riemannian manifold. We investigate the geometry of foliations determined by horizontal and vertical distributions and provide a non-trivial example. We also find a necessary and sufficient condition for a semi-slant submersion to be totally geo...
متن کاملA Geometry Preserving Kernel over Riemannian Manifolds
Abstract- Kernel trick and projection to tangent spaces are two choices for linearizing the data points lying on Riemannian manifolds. These approaches are used to provide the prerequisites for applying standard machine learning methods on Riemannian manifolds. Classical kernels implicitly project data to high dimensional feature space without considering the intrinsic geometry of data points. ...
متن کامل. Measure Contraction Properties of Contact Sub-riemannian Manifolds with Symmetry
Measure contraction properties are generalizations of the notion of Ricci curvature lower bounds in Riemannian geometry to more general metric measure spaces. In this paper, we give sufficient conditions for a contact sub-Riemannian manifold with a one-parameter family of symmetries to satisfy these properties. Moreover, in the special case where the quotient of the contact subRiemannian manifo...
