Let $L$ be the composite field of $K$ and a certain Lubin-Tate extension over $k$ (including the case where $L=K(\\mu_{p^{\\infty}})$). In this paper, we show that there exists an explicitly described constant $C$ in terms of some invariants of $K,k$ and an integer $g \\ge 1$ which satisfies the following property: If $A_{/K}$ is a $g$-dimensional CM abelian variety, then the order of the $p$-torsion subgroup of $A(L)$ is bounded by $C$. We also give a similar bound in the case where $L=K(\\sqrt[p^{\\infty}]{K})$.", "revisions": [ { "version": "v1", "updated": "2023-03-24T00:33:23.000Z" } ], "analyses": { "keywords": [ "adic fields", "lubin-tate extension", "explicit bounds", "dimensional cm abelian variety", "composite field" ], "note": { "typesetting": "TeX", "pages": 0, "language": "en", "license": "arXiv", "status": "editable" } } }
