Generic submanifolds of a locally conformal Kaehler manifold-II

open access: yes, 1993

Toric $G_2$ and nearly Kaehler geometry

open access: yes, 2019
We will discuss analogues of toric geometry in the $G_2$ and nearly Kaehler settings using a multisymplectic generalization of the moment map called the multi-moment map.

Hermitian Yang–Mills equations and pseudo-holomorphic bundles on nearly Kähler and nearly Calabi–Yau twistor 6-manifolds [PDF]

open access: yesNuclear Physics B, 2010
We consider the Hermitian-Yang-Mills (HYM) equations for gauge potentials on a complex vector bundle E over an almost complex manifold X^6 which is the twistor space of an oriented Riemannian manifold M^4. Each solution of the HYM equations on such X^6 defines a pseudo-holomorphic structure on the bundle E.

Nearly Kaehler 6-manifolds with reduced holonomy

open access: yes, 1999
We consider a complete 6-dimensional nearly Kaehler manifold together with the first canonical Hermitian connection. We show that if the holonomy of this connection is reducible, then the manifold endowed with a modified metric and almost complex ...

The Ricci Curvature of Totally Real 3-dimensional Submanifolds of the Nearly Kaehler 6-Sphere

open access: yes, 2007
Let M be a compact 3-dimensional totally real submanifold of the nearly Kaehler 6-sphere. If the Ricci curvature of M satisfies Ric(M) ,thenM is a totally geodesic submanifold ( and Ric(M)# 2)

CR submanifolds of a Kaehler manifold. II

open access: yes, 1979
The differential geometry of CR submanifolds of a Kaehler manifold is studied. Theorems on parallel normal sections and on a special type of flatness of the normal connection on a CR submanifold are obtained.

An optimal inequality on warped product semi-slant submanifolds of nearly Kaehler manifolds

open access: yes, 2014
Non-existence of warped product semi-slant submanifolds of Kaehler manifolds was proved in [17], it is interesting to find their existence. In this paper, we prove the existence of warped product semi-slant submanifolds of nearly Kaehler manifolds by a characterization. To this end we obtain an inequality for the squared norm of second fundamental form
