چکیده
We review the construction of almost contact metric (three-) structures on manifolds with a $G_2$ structure. These are interest for certain supersymmetric configurations in string and M-theory. compute torsion SU(3) structure associated to an ACMS apply these computations heterotic systems supersymmetry enhancement. initiate study space ACM3Ss, which is infinite dimensional local product interesting topological features. Tantalising links between ACM3Ss associative coassociative submanifolds observed.

Contact Structures on 5–manifolds
Using recent work on high dimensional Lutz twists and families of Weinstein structures we show that any almost contact structure on a 5–manifold is homotopic to a contact structure.
متن کاملContact Structures on Elliptic 3-manifolds
We show that an oriented elliptic 3-manifold admits a universally tight positive contact structure if and only if the corresponding group of deck transformations on S3 (after possibly conjugating by an isometry) preserves the standard contact structure. We also relate universally tight contact structures on 3-manifolds covered by S3 to the isomorphism SO(4) = (SU(2) × SU(2))/±1. The main tool u...
متن کاملSemi-slant Pseudo-riemannian Submersions from Indefinite Almost Contact 3-structure Manifolds onto Pseudo-riemannian Manifolds
In this paper, we introduce the notion of a semi-slant pseudoRiemannian submersion from an indefinite almost contact 3-structure manifold onto a pseudo-Riemannian manifold. We investigate the geometry of foliations determined by horizontal and vertical distributions and provide a non-trivial example. We also find a necessary and sufficient condition for a semi-slant submersion to be totally geo...
متن کاملLocal Symmetry of Unit Tangent Sphere Bundle With g- Natural Almost Contact B-Metric Structure
We consider the unit tangent sphere bundle of Riemannian manifold ( M, g ) with g-natural metric G̃ and we equip it to an almost contact B-metric structure. Considering this structure, we show that there is a direct correlation between the Riemannian curvature tensor of ( M, g ) and local symmetry property of G̃. More precisely, we prove that the flatness of metric g is necessary and sufficien...
متن کاملStably and Almost Complex Structures on Bounded Flag Manifolds
We study the enumeration problem of stably complex structures on bounded flag manifolds arising from omniorientations, and determine those induced by almost complex structures. We also enumerate the stably complex structures on these manifolds which bound, therefore representing zero in the complex cobordism ring Ω∗ .
