. We compute Benois L -invariants of weight 1 cuspforms and of their adjoint representations and show how this extends Gross’ p -adic regulator to Artin motives which are not critical in the sense of Deligne. Benois’ construction depends on the choice of a regular submodule which is well understood when the representation is p -regular, as it then amounts to the choice of a “motivic” p -reﬁnement. The situation is dramatically diﬀerent in the p -irregular case, where the regular submodules are…

### On Extra Zeros of p -Adic L -Functions: The Crystalline Case

We formulate a conjecture about extra zeros of p-adic L-functions at near central points which generalizes the conjecture formulated in Benois (Am J Math 133:1573–1632, 2011) to include non-critical

Abstract Let K be an arbitrary number field, and let ρ : Gal($\math{\bar{K}}$/K) → GL2(E) be a nearly ordinary irreducible geometric Galois representation. In this paper, we study the nearly ordinary

### Th\'eorie d'Iwasawa des motifs d'Artin et des formes modulaires de poids 1.

Let $p$ be an odd prime. We study the structure of the cyclotomic Greenberg-Selmer group attached to a general irreducible Artin motive over $\mathbb{Q}$ endowed with an ordinary $p$-stabilization.

### On p-Adic Artin L-Functions II

Let p be a prime. Iwasawa’s famous conjecture relating Kubota-Leopoldt p-adic L-functions to the structure of certain Galois groups has been proven by Mazur and Wiles in Mazur and Wiles (1984). Wiles

Kings, Lei, Loeffler and Zerbes constructed a three-variable Euler system $\kappa({\bf g},{\bf h})$ of Beilinson-Flach elements associated to a pair of Hida families $({\bf g},{\bf h})$ and exploited

### Factorization of p-adic Rankin L-series

We prove that the p-adic L-series of the tensor square of a p-ordinary modular form factors as the product of the symmetric square p-adic L-series of the form and a Kubota–Leopoldt p-adic L-series.
