Universidad de Zaragoza (orcid)0000-0001-9884-7995 Einstein Warped G 2 and Spin(7) Manifolds 2019 In this paper most of the classes of G 2 -structures with Einstein induced metric of negative, null, or positive scalar curvature are realized. This is carried out by means of warped G 2 -structures with fiber an Einstein SU(3) manifold. The torsion forms of any warped G 2 -structure are explicitly described in terms of the torsion forms of the SU(3)-structure and the warping function, which allows to give characterizations of the principal classes of Einstein warped G 2 manifolds. Similar results are obtained for Einstein warped Spin(7) manifolds with fiber a G 2 manifold.
