We introduce natural symmetric cubic tensors and differential forms on these moduli spaces. They correspond to Yukawa couplings and correlation functions in M-theory. We expect that the Yukawa coupling characterizes (co-)associative fibrations on these manifolds. We discuss the Fourier transformation along such fibrations and the analog of the Strominger-Yau-Zaslow mirror conjecture for G2-manifolds. We also discuss similar structures and transformations for Spin(7)-manifolds.", "revisions": [ { "version": "v2", "updated": "2007-12-14T01:28:40.000Z" } ], "analyses": { "keywords": [ "geometric structures", "moduli spaces", "natural symmetric cubic tensors", "strominger-yau-zaslow mirror conjecture", "g2-manifolds" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "inspire": 582720, "adsabs": "2002math......2045L" } } }
