Firstly, we establish complete analogues of Khintchine's theorem and the Jarn\\'ik-Besicovitch theorem for `weighted' simultaneous Diophantine approximation in the $p$-adic case. Secondly, we obtain a lower bound for the Hausdorff dimension of weighted simultaneously approximable points lying on $p$-adic curves. One of the key tools in our proofs is the Mass Transference Principle, including its recent extension due to Wang and Wu. Our result for curves has a natural constraint on the exponents of approximation and, in the case of polynomial curves, complements a theorem of Bugeaud et al, which deals with large exponents.", "revisions": [ { "version": "v1", "updated": "2021-01-13T18:32:31.000Z" } ], "analyses": { "keywords": [ "simultaneous p-adic diophantine approximation", "simultaneously approximable points lying", "mass transference principle", "establish complete analogues", "adic curves" ], "note": { "typesetting": "TeX", "pages": 26, "language": "en", "license": "arXiv", "status": "editable" } } }
