Reeb vector field of almost contact metric structure as affine motion
Дифференциальная геометрия многообразий фигур, 2022 Smooth manifold with almost contact metric structure (i. e., almost contact metric manifold) was considered in this paper. We used a modern version of Cartan’s method of external forms to conduct our study.

Lifting semi-invariant submanifolds to distribution of almost contact metric manifolds
Дифференциальная геометрия многообразий фигур, 2020 Let M be an almost contact metric manifold of dimension n = 2m + 1. The distribution D of the manifold M admits a natural structure of a smooth manifold of dimension n = 4m + 1.

On six-dimensional AH-submanifolds of class W1⊕W2⊕W4 in Cayley algebra
Дифференциальная геометрия многообразий фигур, 2020 Six-dimensional submanifolds of Cayley algebra equipped with an almost Hermitian structure of class W1 W2 W4 defined by means of three-fold vector cross products are considered.

Certain results on almost contact pseudo-metric manifolds [PDF]
Journal of Geometry, 2018 We study the geometry of almost contact pseudo-metric manifolds in terms of tensor fields $$h:=\frac{1}{2}\pounds _\xi \varphi $$h:=12£ξφ and $$\ell := R(\cdot ,\xi )\xi $$ℓ:=R(·,ξ)ξ, emphasizing analogies and differences with respect to the contact ...

Ricci-like solitons on almost contact B-metric manifolds [PDF]
, 2019 Ricci-like solitons with potential Reeb vector field are introduced and studied on almost contact B-metric manifolds. The cases of Sasaki-like manifolds and torse-forming potentials have been considered.

An integral formula for Riemannian G-structures with applications to almost Hermitian and almost contact structures [PDF]
Annals of Global Analysis and Geometry, 2017 For a Riemannian G-structure, we compute the divergence of the vector field induced by the intrinsic torsion. Applying the Stokes theorem, we obtain the integral formula on a closed oriented Riemannian manifold, which we interpret in certain cases.

Existence of compatible contact structures on G₂ -manifolds [PDF]
, 2013 In this paper, we show the existence of (co-oriented) contact structures on certain classes of G(2)-manifolds, and that these two structures are compatible in certain ways.

The topology of Stein fillable manifolds in high dimensions II [PDF]
, 2015 We continue our study of contact structures on manifolds of dimension at least five using complex surgery theory. We show that in each dimension 2q+1 > 3 there are 'maximal' almost contact manifolds to which there is a Stein cobordism from any other (2q ...

ALMOST PSEUDO CONTACT STRUCTURE
Communications of the Korean Mathematical Society, 2011 A new kind of structure is introduced in an even dimen- sional difierentiable Riemannian manifold and some basic properties of this structure is discussed. Also the existence of such structure is shown with an example.
