In this paper we consider the related problems of computing all minimal overorders as well as all overorders of a given order. We use techniques from algorithmic representation theory and the theory of minimal integral ring extensions to obtain efficient and practical algorithms, whose implementation is publicly available.", "revisions": [ { "version": "v1", "updated": "2019-09-24T13:03:40.000Z" } ], "analyses": { "subjects": [ "11Y40", "11R04" ], "keywords": [ "computation", "minimal integral ring extensions", "algorithmic representation theory", "algorithmic number theory", "minimal overorders" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
