Abstract
In this article, we study the Iwasawa theory for Hilbert modular forms over the anticyclotomic extension of a CM field. We prove an one-sided divisibility result toward the Iwasawa main conjecture in this setting. The proof relies on the first and second reciprocity laws relating theta elements to Heegner point Euler systems on Shimura curves. As a by-product we also prove a result towards the rank 0 case of certain Bloch–Kato conjecture and a parity conjecture.
Résumé
Dans cet article, nous étudions la théorie d’Iwasawa pour les formes modulaires de Hilbert sur l’extension anticyclotomique d’un champ CM. Nous prouvons un résultat de divisibilité unilatérale vers la conjecture principale d’Iwasawa dans ce cadre. La preuve repose sur les première et deuxième lois de réciprocité reliant les éléments theta aux systèmes d’Euler de points de Heegner sur les courbes de Shimura. En tant que sous-produit, nous prouvons également un résultat vers le cas de rang 0 d’une certaine conjecture de Bloch–Kato et d’une conjecture de parité.
