Abstract: We study variations of the G_2 structure on the unit tangent sphere bundle, introduced in [Alb2,AlbSal1,AlbSal2] and now called gwistor space. We analize the equations of calibration and coc...

Abstract: We give a presentation of gwistor space. Then we compute the characteristic torsion T^ch of the G_2-twistor space of an oriented Riemannian 4-manifold with constant sectional curvature k and...
