A method is suggested for describing automorphisms of a category of free algebras of this variety. Applying this general method all automorphisms of such categories are found in two cases: 1) for the variety of all free associative K-algebras over an infinite field K and 2) for the variety of all representations of groups in unital R-modules over a commutative associative ring R with unit. It turns out that they are almost inner in a sense.", "revisions": [ { "version": "v1", "updated": "2005-01-20T17:38:32.000Z" } ], "analyses": { "subjects": [ "08B20", "03C05", "16B50", "20C07" ], "keywords": [ "free algebras", "general method", "free associative k-algebras", "universal algebras", "infinite field" ], "note": { "typesetting": "TeX", "pages": 32, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2005math......1331P" } } }
