The main part of the paper, however, is devoted to a general construction for $t$-motives which we call prolongation, and which gives the necessary background for our proof of the algebraic independence. Another incredient is a theorem which shows hypertranscendence for the Anderson-Thakur function $\\omega(t)$, i.e. that $\\omega(t)$ and all its hyperderivatives with respect to $t$ are algebraically independent.", "revisions": [ { "version": "v1", "updated": "2017-10-23T13:10:03.000Z" } ], "analyses": { "subjects": [ "11J93", "11G09", "13N99" ], "keywords": [ "algebraic independence", "prolongation", "period lattice generator", "th tensor power", "algebraically independent" ], "note": { "typesetting": "TeX", "pages": 20, "language": "en", "license": "arXiv", "status": "editable" } } }
