2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/63442We analyse the relationship between the components of the intrinsic torsion of an SU(3) structure on a 6-manifold and a G_2 structure on a 7-manifold. Various examples illustrate the type of SU(3) structure that can arise as a reduction of a metric with holonomy G_2.Proc. conf. Differential Geometry Valencia 2001Differential Geometry53C25; 53C38text
