If for some prime p congruent to 3 mod 4 the p-torsion in the first homology of M is cyclic with odd exponent, then K is of infinite order in the knot concordance group. As one application, recall that the n-twisted double of an arbitrary knot has order 4 in Levine's algebraic concordance group if and only if n is positive and some prime congruent to 3 mod 4 has odd exponent in 4n+1; we show that all such knots are of infinite order in the knot concordance group. As a second application, the 2-bridge knot K(r,s) has infinite order in the knot concordance group if some prime congruent to 3 mod 4 has odd exponent in r.", "revisions": [ { "version": "v1", "updated": "1999-11-30T16:50:04.000Z" } ], "analyses": { "subjects": [ "57M25", "57N70" ], "keywords": [ "knot concordance group", "infinite order", "odd exponent", "prime congruent", "levines algebraic concordance group" ], "tags": [ "journal article" ], "note": { "typesetting": "TeX", "pages": 10, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "1999math.....11241L" } } }
