An explicit arithmetic polygon in terms of the highest two exponents of the polynomial is proved to be a lower bound of the Newton polygon of the $C$-function of the twisted T-adic exponential sum. This bound gives lower bounds for the Newton polygon of the $L$-function of twisted $p$-power order exponential sums.", "revisions": [ { "version": "v1", "updated": "2009-12-10T07:49:32.000Z" } ], "analyses": { "subjects": [ "11L07", "11F30" ], "keywords": [ "twisted exponential sums", "polynomial", "power order exponential sums", "newton polygon", "lower bound" ], "tags": [ "journal article" ], "publication": { "doi": "10.1007/s11425-010-3144-2", "journal": "Science in China A: Mathematics", "year": 2010, "month": "May", "volume": 53, "number": 9, "pages": 2395 }, "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2010ScChA..53.2395L" } } }
