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.2019http://zaguan.unizar.es/record/13093910.1007/s00220-019-03355-1http://zaguan.unizar.es/record/130939oai:zaguan.unizar.es:130939info:eu-repo/grantAgreement/ES/DGA/E22-17Rinfo:eu-repo/grantAgreement/ES/MINECO/MTM2017-85649-PCommunications in Mathematical Physics 369, 2 (2019), 637-673All rights reservedhttp://www.europeana.eu/rights/rr-f/info:eu-repo/semantics/openAccess
