Pointwise hemi-slant warped product submanifolds in nearly Kaehler manifolds

Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica
In this paper, we introduce the notion of pointwise hemi-slant sub-manifolds of nearly Kaehler manifolds. Further, we study their warped products and prove the necessary and sufficient condition that a point-wise hemi-slant submanifold to be a warped ...

DUAL TIMELIKE NORMAL AND DUAL TIMELIKE SPHERICAL CURVES IN DUAL MINKOWSKI SPACE

, 2019
: In this paper, we give characterizations of dual timelike normal and dual timelike spherical curves in the dual Minkowski 3-space and we show that every dual timelike normal curve is also a dual timelike spherical curve.Keywords: Normal curves, Dual ...

The Semiring of Immersions of Manifolds

, 1993
. In [2], [3], [4], [5] B.-Y. Chen introduced the tensor product immersion of a given Riemannian manifold. In this paper we study the tensor product of two immersions of differentiable manifolds.

Shape Operators of Orbits of Isotropy Subgroups in Riemannian Symmetric Spaces of the Compact Type

, 1995
. In the present paper orbits of isotropy subgroups are discussed in symmetric spaces of the compact type. Shape operators of the orbits are described by using the root space decompositions of orthogonal symmetric Lie algebras.

On the Spinor Representation of Surfaces in Euclidean 3-Space.

, 1997
The aim of the present paper is to clarify the relationship between immersions of surfaces and solutions of the Dirac equation. The main idea leading to the description of a surface M 2 by a spinor field is the observation that the restriction to M 2
