As a generalization of the classical Iwasawa main conjecture, they prove a relationship between analytic objects (a pair of Katz's $2$-variable $p$-adic $L$-functions) and algebraic objects (two \"everywhere unramified\" Iwasawa modules) involving codimension two cycles in a $2$-variable Iwasawa algebra. We prove an analogous result by considering the restriction to an imaginary quadratic field $K$ (where an odd prime $p$ splits) of an elliptic curve $E$, defined over $\\mathbb{Q}$, with good supersingular reduction at $p$. On the analytic side, we consider eight out of the ten pairs of $2$-variable $p$-adic $L$-functions in this setup (four of the five $2$-variable $p$-adic $L$-functions have been constructed by Loeffler and the fifth $2$-variable $p$-adic $L$-function is due to Hida). On the algebraic side, we consider modifications of fine Selmer groups over the $\\mathbb{Z}_p^2$-extension of $K$. We also provide numerical evidence, using algorithms of Pollack, towards a pseudo-nullity conjecture of Coates-Sujatha.", "revisions": [ { "version": "v1", "updated": "2018-06-19T13:33:41.000Z" } ], "analyses": { "subjects": [ "11R23", "11G05", "11G07", "11R34", "11S25" ], "keywords": [ "supersingular reduction", "elliptic curve", "higher codimension iwasawa theory", "fine selmer groups", "imaginary quadratic field" ], "note": { "typesetting": "TeX", "pages": 57, "language": "en", "license": "arXiv", "status": "editable" } } }
