Feb 15, 2015 at 18:17 | comment | added | Oldřich Spáčil | The following paper might be helpful: Cadek, Crabb, Vanzura: Obstruction theory on 8-manifolds, doi: 10.1007/s00229-008-0203-x, arXiv:0710.0734. They give a necessary and sufficient condition for existence of a $U(4)$-structure (Proposition 4.1) as well as for some other $G$-structures. | |
