A classical result of Kolyvagin states that, under suitable assumptions, if the basic Heegner point $y_K \\in E(K)$ is not divisible by an odd prime $p$, then the groups $E(K)/{\\bf Z} y_K$ and $\\sha(E/K)$ are finite and their orders are prime to $p$. In this article we develop the following themes: firstly, we discuss improvements of Kolyvagin's result, following Cha (2005) and Lawson and Wuthrich (2016). Secondly, we prove an abstract Iwasawa-theoretical result which allows us to deduce, under several additional assumptions, that similar vanishing holds for all layers in the anticyclotomic ${\\bf Z}_p$-extension of $K$. Analogous results hold for CM points on simple quotients of Jacobians of Shimura curves over totally real fields; this will be discussed in a separate article.", "revisions": [ { "version": "v1", "updated": "2018-08-28T20:58:16.000Z" } ], "analyses": { "subjects": [ "11G05", "11G18", "11G40" ], "keywords": [ "anticyclotomic iwasawa theory", "kolyvagins result", "consequences", "basic heegner point", "totally real fields" ], "note": { "typesetting": "TeX", "pages": 32, "language": "en", "license": "arXiv", "status": "editable" } } }
