Manifolds with almost contact 3-structure and metrics of Hermitian–Norden type [PDF]

Journal of Geometry, 2017
It is introduced a differentiable manifold with almost contact 3-structure which consists of an almost contact metric structure and two almost contact B-metric structures. The product of this manifold and a real line is an almost hypercomplex manifold with Hermitian-Norden metrics.

Pair of Associated η-Ricci–Bourguignon Almost Solitons with Vertical Potential on Sasaki-like Almost Contact Complex Riemannian Manifolds

Mathematics
The manifolds studied are almost contact complex Riemannian manifolds, known also as almost contact B-metric manifolds. They are equipped with a pair of pseudo-Riemannian metrics that are mutually associated to each other using an almost contact ...

Almost contact metric structures induced by G2G2 structures

, 2017
We study almost contact metric structures induced by 2-fold vector cross products on manifolds with G2 structures. We get some results on possible classes of almost contact metric structures. Finally, we give examples.

Pseudo-Slant Submanifolds of a Generalised Almost Contact Metric Structure Manifold

Journal of the Tensor Society, 2007
In this paper we have studied pseudo-slant submanifolds of a Generalised almost contact metric structure manifold and established integrability conditions of distributions and some interesting results on this submanifold.

On the almost contact metric structure of cosymplectic type on a hypersurface of a Kähler manifold

Дифференциальная геометрия многообразий фигур, 2018
It is proved that the matrix of the second fundamental form of the immersion of a hypersurfaces of a Kähler manifold, equipped with an almost contact metric structure of cosymplectic type, is of special kind.

On Almost Contact Metric Structures of Cosymplectic Type

, 2017
1. As it is known, the almost contact metric structure on an odd-dimensional manifold N is de ned by the system of tensor elds f; ; ; gg on this manifold, where is a vector eld, is a covector eld, is a tensor of the type 1; 1 and g = h; i is the Riemannian metric [5], [6]. Moreover, the following conditions are ful lled: = 1; = 0; = 0; 2 = ?id + nbsp;;
