  • Fitting ideals of p-ramified Iwasawa modules over totally real fields

    Cornelius Greither, Takenori Kataoka, Masato Kurihara

    Selecta Mathematica (Selecta Mathematica, New Series)  28 ( 1 ) 1 - 48 2022.02

    Research paper (scientific journal), Joint Work, Accepted,  ISSN  10221824

     View Summary

    We completely calculate the Fitting ideal of the classical p-ramified Iwasawa module for any abelian extension K/k of totally real fields, using the shifted Fitting ideals recently developed by the second author. This generalizes former results where we had to assume that only p-adic places may ramify in K/k. One of the important ingredients is the computation of some complexes in appropriate derived categories.

  • Notes on the dual of the ideal class groups of CM-fields

    Masato Kurihara

    Journal de Théorie des Nombres de Bordeaux (Journal de Theorie des Nombres de Bordeaux)  33 ( 3.2 ) 971 - 996 2021

    Research paper (scientific journal), Single Work, Accepted,  ISSN  12467405

     View Summary

    In this paper, for a CM abelian extension K/k of number fields, we propose a conjecture which describes completely the Fitting ideal of the minus part of the Pontryagin dual of the T-ray class group of K for a set T of primes as a Gal(K/k)-module. Here, we emphasize that we consider the full class group, and do not throw away the ramifying primes (the object we study is not the quotient of the class group by the subgroup generated by the classes of ramifying primes). We prove that our conjecture is a consequence of the equivariant Tamagawa number conjecture, and also prove the Iwasawa theoretic version of our conjecture.

  • On the refined conjectures on Fitting ideals of Selmer groups of elliptic curves with supersingular reduction

    Chan-Ho Kim and Masato Kurihara

    International Mathematics Research Notices (International Mathematics Research Notices)  2021 ( 14 ) 10559 - 10599 2021.07

    Research paper (scientific journal), Joint Work, Accepted,  ISSN  10737928

     View Summary

    In this paper, we study the Fitting ideals of Selmer groups over finite subextensions in the cyclotomic $\mathbb{Z}_p$-extension of $\mathbb{Q}$ of an elliptic curve over $\mathbb{Q}$. Especially, we present a proof of the "weak main conjecture"à la Mazur and Tate for elliptic curves with good (supersingular) reduction at an odd prime $p$. We also prove the "strong main conjecture"suggested by the second named author under the validity of the $\pm $-main conjecture and the vanishing of a certain error term. The key idea is the explicit comparison among "finite layer objects", "$\pm $-objects", and "fine objects"in Iwasawa theory. The case of good ordinary reduction is also treated.
