Almost contact metric and metallic Riemannian structures

open access: yesCommunications Faculty Of Science University of Ankara Series A1Mathematics and Statistics, 2020
Summary: The metallic structure is a fascinating topic that continually generates new ideas. In this work, new metallic manifolds are constructed starting from both almost contact metric manifolds and we obtain some important notions like the metallic deformation. We show that there exists a correspondence between the metallic Riemannian structures and

Almost contact metric 3-submersions

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1984
An almost contact metric 3-submersion is a Riemannian submersion, π from an almost contact metric manifold (M4m+3,(φi,ξi,ηi)i=13,g) onto an almost quaternionic manifold (N4n,(Ji)i=13,h) which commutes with the structure tensors of type (1,1);i.e., π*φi ...

Pair of associated Schouten-van Kampen connections adapted to an almost contact B-metric structure

open access: yes, 2015
There are introduced and studied a pair of associated Schouten-van Kampen affine connections adapted to the contact distribution and an almost contact B-metric structure generated by the pair of associated B-metrics and their Levi-Civita connections.

Canonical-type connection on almost contact manifolds with B-metric

open access: yes, 2013
The canonical-type connection on the almost contact manifolds with B-metric is constructed. It is proved that its torsion is invariant with respect to a subgroup of the general conformal transformations of the almost contact B-metric structure. The basic

Almost Contact Metric Structures on 5-Dimensional Nilpotent Lie Algebras [PDF]

open access: yesSymmetry, 2016
We study almost contact metric structures on 5-dimensional nilpotent Lie algebras and investigate the class of left invariant almost contact metric structures on corresponding Lie groups. We determine certain classes that a five-dimensional nilpotent Lie group can not be equipped with.

Examples of Almost Para-Contact Metric Structures on 5-dimensions

open access: yesFundamental Journal of Mathematics and Applications, 2022
In this study, the classes of several almost paracontact metric structures on 5 dimensional nilpotent Lie algebras are determined. It is also shown that there are no $\eta-$ Einstein structures on 5 dimensional nilpotent Lie algebras.

On some Lie groups as 5-dimensional almost contact B-metric manifolds with three natural connections [PDF]

open access: yes, 2014
Almost contact manifolds with B-metric are considered. There are studied three natural connections (i.e. linear connections preserving the structure tensors) determined by conditions for their torsions.

Almost Contact B-Metric Structure on 5-Dimensional Nilpotent Lie algebras

open access: yesInternational Electronic Journal of Geometry, 2020
The classification of almost contact $B-$metric manifolds is considered. It is shown that $\mathcal{D}-$homothetic deformation of these manifolds in the class $\mathcal{F}_{i}$ $\left( i=0,1,4,5\right) $ remains in the same the class $\mathcal{F}_{i}$. We study almost contact $B-$metric structure on $5-$dimensional nilpotent Lie algebras. The class of
