We prove closure under direct products in the monoid case, and free products in the group case. We also show that the automorphism group of a full shift embeds in that of an uncountable sofic shift. Some undecidability results are obtained as corollaries.", "revisions": [ { "version": "v1", "updated": "2015-07-03T05:49:10.000Z" } ], "analyses": { "keywords": [ "automorphism group", "full shift embeds", "uncountable sofic shift", "endomorphism monoid", "direct products" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "2015arXiv150700820S" } } }
