Our main observation is that, for every non-negative integer $n$, the $p$-adic trace defines an isomorphism of abelian groups between local systems whose order divides $(p-1)p^n$ and $\\ell$-adic characters of the multiplicative group of $p$-adic integers of depth less than or equal to $n$.", "revisions": [ { "version": "v2", "updated": "2011-06-14T17:18:13.000Z" } ], "analyses": { "subjects": [ "20C15", "14G15" ], "keywords": [ "continuous characters", "geometrization", "multiplicative group", "rank-one local systems", "adic trace defines" ], "note": { "typesetting": "TeX", "pages": 3, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2010arXiv1012.0213C" } } }
