As in the Carlitz case, we give a description of these extensions in terms of evaluations of Anderson generating functions and their hyperderivatives at roots of unity. We also give a direct proof that the image of the Galois representation attached to the $\\mathfrak{p}$-adic Tate module lies in the $\\mathfrak{p}$-adic points of the motivic Galois group. This is a generalization of the corresponding result of Chang and Papanikolas for the $t$-adic case.", "revisions": [ { "version": "v1", "updated": "2020-08-17T07:59:24.000Z" } ], "analyses": { "subjects": [ "11J93" ], "keywords": [ "anderson generating functions", "drinfeld torsion extensions", "taylor coefficients", "carlitz prime power torsion extension", "adic tate module lies" ], "note": { "typesetting": "TeX", "pages": 14, "language": "en", "license": "arXiv", "status": "editable" } } }
