We prove that, for all sufficiently large finite non-abelian simple groups G, there exist subsets C of v(G) and D of w(G) of size such that every element of G can be realized in at least one way as the product of an element of C and an element of D and the average number of such representations is O(log |G|). In particular, if w is a fixed nontrivial word and G is a sufficiently large finite non-abelian simple group, then w(G) contains a thin base of order 2. This is a non-abelian analogue of a result of Van Vu for the classical Waring problem. Further results concerning thin bases of G of order 2 are established for any finite group and for any compact Lie group G.", "revisions": [ { "version": "v1", "updated": "2013-12-17T23:13:14.000Z" } ], "analyses": { "subjects": [ "20D06", "11B13", "11P05", "20C33", "22C05" ], "keywords": [ "finite simple groups", "refined waring problem", "large finite non-abelian simple group", "sufficiently large finite non-abelian simple", "thin base" ], "note": { "typesetting": "TeX", "pages": 20, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2013arXiv1312.4998L" } } }
