Abstract

We reduce the embedding problem for hypo SU(2) and SU(3)-structures to the embedding problem for hypo G2-structures into parallel Spin(7)-manifolds. The latter will be described in terms of gauge deformations. This description involves the intrinsic torsion of the initial G2-structure and allows us to prove that the evolution equations, for all of the above embedding problems, do not admit non-trivial longtime solutions.<br />Comment: corrected Lemma 3.9, new description of SU(2)-structures in dimension five, included a section on the Cauchy-Kowalevski theorem and integral curves in Frechet spaces
