We continue the study of Selmer groups associated with an Artin representation endowed with a p-stabilization which was initiated in arXiv:1811.05368. We formulate a main conjecture and an extra zeros conjecture at all unramified odd primes p, which are shown to imply the p-part of the Tamagawa number conjecture for Artin motives at s=0. We also relate our new conjectures with various cyclotomic Iwasawa main conjectures and p-adic Stark conjectures that appear in the literature. In particular, they provide a natural interpretation for recent conjectures on p-adic L-functions attached to (the adjoint of) a weight one modular form. In the case of monomial representations, we prove that our conjectures are essentially equivalent to some newly introduced Iwasawa-theoretic conjectures for Rubin-Stark elements. [less ▲]

La théorie d’Iwasawa s’intéresse à la construction d’un analogue p-adique analytique de la fonction L complexe d’un motif M, et à son interprétation en terme de l’arithmétique de M. Bien que de nature p-adique, elle a des applications à des problèmes globaux tels que la conjecture de Birch et Swinnerton-Dyer. Nous discutons ici du cas des motifs attachés à des représentations d’Artin sur Q, et plus particulièrement à la représentation de Deligne-Serre d’une forme modulaire primitive de poids 1. [less ▲]

Let p be an odd prime. We study the structure of the cyclotomic Greenberg-Selmer group attached to a general irreducible Artin motive over Q endowed with an ordinary p-stabilization. Under the Leopoldt and the weak p-adic Schanuel Conjectures, we show that it is of torsion over the Iwasawa algebra. Under mild hypotheses on p we compute the constant term of its characteristic series in terms of a p-adic regulator and we highlight an extra zeros phenomenon. We then focus on Artin motives attached to classical weight one modular forms, to which our preceding results apply unconditionally. We formulate an Iwasawa Main Conjecture in this context and prove one divisibility using a Theorem of Kato. [less ▲]
