Comments welcome", "categories": [ "math.RT" ], "abstract": "Let \\chi be an irreducible character of the finite group G. If g is an element of G and \\chi(g) is not zero, then we conjecture that the order of g divides |G|/\\chi(1). The conjecture is a generalization of the classical fact that irreducible p-projective characters vanish on p-singular elements, since the latter is equivalent to saying that if \\chi(g) is not zero then the square free part of the order of g divides |G|/\\chi(1). We prove some partial results on the conjecture; in particular, we show that the order of g divides (|G|/\\chi(1))^2. Using these results, we derive some bounds on heights of characters. We also pose a related conjecture concerning congruences satisfied by central character values.", "revisions": [ { "version": "v1", "updated": "2006-04-14T14:26:33.000Z" } ], "analyses": { "subjects": [ "20C15", "20C20" ], "keywords": [ "finite group", "central character values", "square free part", "related conjecture concerning congruences" ], "note": { "typesetting": "TeX", "pages": 12, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2006math......4337W" } } }
