In this paper we develop an algebraic theory that creates a connection between these approaches. Our main method is to take the ultra product of abelian groups and to develop a precise algebraic theory of higher order characters on it. These results then can be turned back into approximative statements about finite Abelian groups.", "revisions": [ { "version": "v1", "updated": "2009-03-05T02:43:52.000Z" } ], "analyses": { "keywords": [ "higher order fourier analysis", "hyper graph regularity method", "finite abelian groups", "higher order characters", "szemeredi type theorems" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2009arXiv0903.0897S" } } }
