Moreover, different orderings of number fields affect the answers of such questions in a nontrivial way. So, in this paper, we set up an invariant of number fields with parameters, and consider field counting problems with specifications while the parameters change as a variable. The case of abelian extensions shows that, roughly speaking, the result of counting abelian fields is a function of the invariant with parameters.", "revisions": [ { "version": "v1", "updated": "2023-08-22T12:37:59.000Z" } ], "analyses": { "keywords": [ "abelian extensions", "class groups", "distribution", "number fields affect", "parameters change" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
