A study on pseudoparallel submanifolds of generalized Lorentz-Sasakian forms

In this article, pseudoparallel submanifolds for generalized Lorentz-Sasakian space forms are investigated. Submanifolds of these manifolds with properties such as pseudoparallel, 2-pseudoparallel, Ricci generalized pseudoparallel, and 2-Ricci ...

Holomorphic Distributions on a Generic Submanifold [PDF]

application/pdfAn integral formula for the Ricci tensor of a generic submanifold immersed in a complex projective space is given. As an application, the relation of the integrability condition of theholomorphic distribution and the Ricci curvature of a ...

Critical points of the distance function to a generic submanifold [PDF]

International audienceIn general, the critical points of the distance function d_M to a compact submanifold M ⊂ R^D can be poorly behaved. In this article, we show that this is generically not the case by listing regularity conditions on the critical and

Intrinsic and Extrinsic Geometry of Pseudoparallel Submanifolds in Almost Kenmotsu (κ, μ, ν)-Manifolds

In this paper, we undertake a detailed study of pseudoparallel submanifolds of almost Kenmotsu (κ,μ,ν)-spaces, with particular emphasis on invariant submanifolds.

On generic submanifold of Sasakian manifold with concurrent vector field

, 2019
In the present paper, we deal with the generic submanifold admitting a Ricci soliton in Sasakian manifold endowed with concurrent vector field. Here, we find that there exists never any concurrent vector field on the invariant distribution D of generic ...

Scalar curvature, inequality and submanifold

, 1973
Using an inequality relation between scalar curvature and length of second fundamental form, we may conclude that a submanifold must have nonnegative (or positive) sectional curvatures. An application to compact submanifolds in obtained.

A Kernel Based Neighborhood Discriminant Submanifold Learning for Pattern Classification

, 2014
We propose a novel method, called Kernel Neighborhood Discriminant Analysis (KNDA), which can be regarded as a supervised kernel extension of Locality Preserving Projection (LPP).
