A CR twistor space of a G2-manifold.

Differential Geometry and its Application. 2011. Vol. 29. No. 1. P. 101-107.

Let M be a G2-manifold. We consider an almost CR-structure on the sphere bundle of unit tangent vectors on M, called the CR twistor space. This CR-structure is integrable if and only if M is a holonomy G2 manifold. We interpret G2-instanton bundles as CR-holomorphic bundles on its twistor space.
