The arithmetic partial derivative with respect to a prime $p$ is the $p$-th component of the arithmetic derivative. In this paper, we generalize the arithmetic partial derivative to $p$-adic fields (the local case) and the arithmetic derivative to number fields (the global case). We study the dynamical system of the $p$-adic valuation of the iterations of the arithmetic partial derivatives. We also prove that for every integer $n\\geq 0$, there are infinitely many elements with exactly $n$ anti-partial derivatives. In the end, we study the $p$-adic continuity of arithmetic derivatives.", "revisions": [ { "version": "v1", "updated": "2023-07-10T21:34:51.000Z" } ], "analyses": { "subjects": [ "11A25", "11R04" ], "keywords": [ "arithmetic derivative", "adic fields", "number fields", "arithmetic partial derivative", "generalization" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
