On nearly parallel G2-structures
[摘要] A nearly parallel G(2)-structure on a seven-dimensional Riemannian manifold is equivalent to a spin structure with a Killing spinor. We prove general results about the automorphism group of such structures and we construct new examples. We classify ail nearly parallel Gz-manifolds with large symmetry group and in particular all homogeneous nearly parallel G(2)-structures.
