Integrability of Reeb Distribution Associated to a Generalized Engel Manifold

Journal of Mathematics, Volume 2026, Issue 1, 2026.
In this paper, we define a generalized Reeb distribution of an Engel 4n‐manifold and give a necessary and sufficient condition for integrability of this Reeb distribution which gives a generalization of some results of N. Pia about Reeb distributions of Engel 4‐manifolds.

The Schouten-van Kampen affine connection adapted to an almost (para) contact metric structure

, 2013
We study the Schouten-van Kampen connection associated to an almost contact or paracontact metric structure. With the help of such a connection, some classes of almost (para) contact metric manifolds are characterized.

3-Sasakian manifolds, 3-cosymplectic manifolds and Darboux theorem

, 2007
We present a compared analysis of some properties of 3-Sasakian and 3-cosymplectic manifolds. We construct a canonical connection on an almost 3-contact metric manifold which generalises the Tanaka-Webster connection of a contact metric manifold and we ...

Locally Conformal Almost Cosymplectic Manifolds Endowed with a Skew-Symmetric Killing Vector Field [PDF]

, 2004
We study a locally conformal almost cosymplectic manifold M which carries a horizontal skew-symmetric Killing vector field X. Such X denes a relative conformal cosymplectic transformation of the conformal cosymplectic 2-form Ω of M and the square of its ...

On Slant Riemannian Submersions For Cosymplectic Manifolds [PDF]

, 2013
In this paper we introduce slant Riemannian submersions from cosymplectic manifolds onto Riemannian manifolds. We obtain some results on slant Riemannian submersions of a cosymplectic manifolds.

On the harmonicity of normal almost contact metric structures

, 2011
We consider normal almost contact structures on a Riemannian manifold and, through their associated sections of an ad-hoc twistor bundle, study their harmonicity, as sections or as maps.
