Yang-Mills Flows on Nearly Kähler Manifolds and G 2-Instantons [PDF]

open access: yesCommunications in Mathematical Physics, 2010
We consider Lie(G)-valued G-invariant connections on bundles over spaces G/H, RxG/H and R^2xG/H, where G/H is a compact nearly Kaehler six-dimensional homogeneous space, and the manifolds RxG/H and R^2xG/H carry G_2- and Spin(7)-structures, respectively.

Pseudoholomorphic curves in nearly Kaehler Manifolds

open access: yes, 2021
The most natural maps into nearly Kaehler manifolds are pseudoholomorphic curves. When taking the cone of a nearly Kaehler manifold one gets a torsion-free $G_2$ manifold, and the cone of a pseudoholomorphic curve will be an associative submanifold. Most

Dimensional reduction of the heterotic string over nearly-Kähler manifolds

open access: yesJournal of High Energy Physics, 2009
Our aim is to derive the effective action in four dimensions resulting by reducing dimensionally the ten-dimensional ${\cal N}=1$ heterotic supergravity coupled to ${\cal N}=1$ super Yang-Mills over manifolds admitting a nearly-Kähler structure.

Submersions of generic submanifolds of a Kaehler manifold

open access: yes, 2014
Kobayashi has shown that for the submersion π:M→B of a CR-submanifold of a Kaehler manifold M¯ onto an almost Hermitian manifold B,B is necessarily a Kaehler manifold.

On CR-Lightlike Product of an Indefinite Kaehler Manifold [PDF]

open access: yes, 2011
We have studied mixed foliate CR-lightlike submanifolds and CR-lightlike product of an indefinite Kaehler manifold and also obtained relationship between them.

Clairaut anti-invariant submersion from nearly Kaehler manifold

open access: yes, 2020
In the present paper, we investigate geometric properties of Clairaut anti-invariant submersions whose total space is a nearly Kaehler manifold. We obtain condition for Clairaut anti-invariant submersion to be a totally geodesic map and also study Clairaut anti-invariant submersions with totally umbilical fibers.

Some submersions of CR-hypersurfaces of Kaehler-Einstein manifold [PDF]

open access: yes, 2003
The Riemannian submersions of a CR-hypersurface M of a Kaehler-Einstein manifold M˜ are studied. If M is an extrinsic CR-hypersurface of M˜, then it is shown that the base space of the submersion is also a Kaehler-Einstein ...

Warped product pointwise semi-slant submanifolds of nearly Kaehler manifolds

open access: yesFilomat
In this paper, we study warped pointwise semi-slant submanifolds of nearly Kaehler manifolds. We prove that there do not exist non-trivial warped product pointwise semi-slant submanifolds of the form N?? f NT in a nearly Kaehler manifold ?M but the geometry of warped products by reversing these two factors is similar to the case of general ...
