On almost contact metric hypersurface of a Kahler manifold

Proceedings of the Indian Academy of Sciences - Section A, 1974
We have studied the normality of an almost contact metric hypersurface of a Kahler manifold. Quasi-umbilical and umbilical properties have also been studied.

On 2-almost contact tachibana manifolds

Rendiconti del Circolo Matematico di Palermo, 2001
A Tachibana manifold is a \((2n+2)\)-dimensional Riemannian manifold equipped with \(2\) structure vector fields \(\xi _{2m+1}\), \(\xi _{2m+2}\), such that the \(2\)-form \(\varphi =\eta ^{2m+1}\wedge \eta ^{2m+2}\) is harmonic, \(\eta ^r\) being the \(1\)-form dual to \(\xi _r\), \(r+2m+1,2m+2\) [\textit{S. Tachibana}, Tensor New Ser.

Almost contact 5-manifolds are contact

Annals of Mathematics, 2015
The main result proved in the paper: On a closed oriented 5-dimensional manifold, there exists a contact structure in every homotopy class of almost contact structures. Using the techniques developed in this article, it is not possible to conclude anything about the number of distinct contact distributions that may occur in a given homotopy class of ...

Almost Contact Metric Structures on the Hypersurface of Almost Hermitian Manifolds

Journal of Mathematical Sciences, 2015
This is a review paper on the theories of almost contact, almost Hermitian and Kenmotsu structures and their use in classical differential geometry. The authors give a very comprehensive account on the historical development of these structures using only Riemannian metrics, although modern applicable studies on these structures have been extended ...
