We establish a correspondence between the isomorphism classes of these extensions and some Kummer extensions of a suitable field F containing K. We then describe such classes in terms of the representations of Gal(F/K). Finally, for k = 2 and for each possible Galois group G, we count the number of isomorphism classes of the extensions whose normal closure has a Galois group isomorphic to G. As a byproduct, we get the total number of isomorphism classes.", "revisions": [ { "version": "v1", "updated": "2016-01-22T10:15:04.000Z" } ], "analyses": { "subjects": [ "11S20", "11S15" ], "keywords": [ "p-adic field", "wild extensions", "isomorphism classes", "galois group isomorphic", "normal closure" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
