In the present paper, we introduce a new class of structures on an even dimensional
differentiable Riemannian manifold which combines, well known in literature, the Sasakian …

We investigate normal magnetic curves in (2 n+ s)-dimensional homothetic s-th Sasakian
manifolds as a generalization of S-manifolds. We show that a curve γ is a normal magnetic …

In this thesis, we characterized a new class of almost contact metric (ACR−) manifolds and
establish the equivalent conditions that characterize its identity in sense of Kirichenko's …

The present paper is devoted to a class of manifolds which admit an f-structure with 2-
dimensional parallelizable kernel. Such manifolds are called 4-dimensional almost bi …

In this paper, we determine the components of the Weyl tensor of almost contact metric (ACR-
) manifold of class C12 on associated G-structure (AG-structure) space. As an application …

We study hypersurfaces isometrically immersed in a trans-S-manifolds in order to find out
under what conditions they could inherit the structure of the ambient manifold and so, to …

In the present paper, we introduce a new class of structures on an even dimensional
differentiable Riemannian manifold which combines, well known in literature, the Sasakian …

We prove that if the f-sectional curvature at any point of a (2n+ s)-dimensional metric f-
contact manifold satisfying the (κ, µ) nullity condition with n> 1 is independent of the f-section …

В данной работе мы определяем компоненты тензора Вейля почти контактного
