• #### L-invariants and Darmon cycles attached to higher weight modular forms ﻿

(2012)
Article
Open Access
Let f be a modular eigenform of even weight k=2 and new at a prime p dividing exactly the level with respect to an indefinite quaternion algebra. The theory of Fontaine-Mazur allows to attach to f a monodromy module DFMf ...
• #### Special values of L-functions and the arithmetic of Darmon points ﻿

(2013)
Article
Open Access
Building on our previous work on rigid analytic uniformizations, we introduce Darmon points on Jacobians of Shimura curves attached to quaternion algebras over and formulate conjectures about their rationality properties. ...
• #### On the Elliptic Stark Conjecture in higher weight ﻿

(2020-01-01)
Article
Open Access
We study the special values of the triple product p-adic L-function constructed by Darmon and Rotger at all classical points outside the region of interpolation. We propose conjectural formulas for these values that can ...
• #### On some classes of irreducible polynomials ﻿

Article
Restricted access - publisher's policy
One of the fundamental tasks of Symbolic Computation is the factorization of polynomials into irreducible factors. The aim of the paper is to produce new families of irreducible polynomials, generalizing previous results ...
• #### Factorization and Malleability of RSA Moduli, and Counting Points on Elliptic Curves Modulo N ﻿

(Multidisciplinary Digital Publishing Institute (MDPI), 2020-11-27)
Article
Open Access
In this paper we address two different problems related with the factorization of an RSA (Rivest–Shamir–Adleman cryptosystem) modulus N. First we show that factoring is equivalent, in deterministic polynomial time, to ...
• #### On rigid analytic uniformizations of Jacobians of Shimura curves ﻿

(2012)
Article
Open Access
The main goal of this article is to give an explicit rigid analytic uniformization of the maximal toric quotient of the Jacobian of a Shimura curve over Q at a prime dividing exactly the level. This result can be viewed ...
• #### The right-generators descendant of a numerical semigroup ﻿

(2020-01-01)
Article
Open Access
For a numerical semigroup, we encode the set of primitive elements that are larger than its Frobenius number and show how to produce in a fast way the corresponding sets for its children in the semigroup tree. This allows ...
• #### On the elliptic Stark conjecture at primes of multiplicative reduction ﻿

(2019-01-01)
Article
Open Access
In [DLR], Darmon, Lauder, and Rotger formulated a p-adic elliptic Stark conjecture for the twist of an elliptic curve E/Q by the self-dual tensor product ¿ ¿ of two odd and two-dimensional Artin representations. These ...

Article
Open Access
Let $X(D,1) =\Gamma(D,1) \backslash \mathbb{H}$ denote the Shimura curve of level $N=1$ arising from an indefinite quaternion algebra of fixed discriminant $D$. We study the discrete average of the error term in the ...
