  • Computation of numerical semigroups by means of seeds 

    Bras Amorós, Maria; Fernández González, Julio (2018-09-01)
    Article
    Accés obert
    For the elements of a numerical semigroup which are larger than the Frobenius number, we introduce the definition of seed by broadening the notion of generator. This new concept allows us to explore the semigroup tree in ...
  • Stark points and p-adic iterated integrals attached to modular forms of weight one 

    Darmon, Henri; Lauder, Alan; Rotger Cerdà, Víctor (Cambridge University Press, 2015-01-01)
    Article
    Accés obert
    Let be an elliptic curve over , and let and be odd two-dimensional Artin representations for which is self-dual. The progress on modularity achieved in recent decades ensures the existence of normalized eigenforms , , and ...
  • Beilinson-Flach elements and Euler systems II: p-adic families and the Birch and Swinnerton-Dyer conjecture 

    Bertolini, Massimo; Darmon, Henri; Rotger Cerdà, Víctor (2015-03-23)
    Article
    Accés obert
    Let E be an elliptic curve over Q and let % be an odd, irreducible twodimensional Artin representation. This article proves the Birch and Swinnerton-Dyer conjecture in analytic rank zero for the Hasse-WeilArtin L-series ...
  • Gross-Stark units and p-adic iterated integrals attached to modular forms of weight one 

    Darmon, Henri; Lauder, Alan; Rotger Cerdà, Víctor (2016-08-01)
    Article
    Accés obert
    This article can be read as a companion and sequel to the authors’ earlier article on Stark points and p-adic iterated integrals attached to modular forms of weight one, which proposes a conjectural expression for the ...
  • Elliptic curves of rank two and generalized Kato classes 

    Darmon, Henri; Rotger Cerdà, Víctor (2016-08-24)
    Article
    Accés obert
    Heegner points play an outstanding role in the study of the Birch and Swinnerton-Dyer conjecture, providing canonical Mordell–Weil generators whose heights encode first derivatives of the associated Hasse–Weil L-series. ...
  • On the rank and the convergence rate toward the Sato-Tate measure 

    Fite Naya, Francesc; Guitart Morales, Xavier (2017-10-16)
    Article
    Accés restringit per política de l'editorial
    Let A be an abelian variety defined over a number field and let G denote its Sato–Tate group. Under the assumption of certain standard conjectures on L -functions attached to the irreducible representations of G, we study ...
  • Stark points and the Hida-Rankin p-adic L-function 

    Casazza, Daniele; Rotger Cerdà, Víctor (2018-02)
    Article
    Accés restringit per política de l'editorial
    This article is devoted to the elliptic Stark conjecture formulated by Darmon (Forum Math Pi 3:e8, 2015), which proposes a formula for the transcendental part of a p-adic avatar of the leading term at s=1 of the Hasse–Weil–Artin ...
  • On the Sato-Tate conjecture for non-generic abelian surfaces 

    Johansson, Christian; Fite Naya, Francesc (2017-01)
    Article
    Accés obert
    We prove many non-generic cases of the Sato-Tate conjecture for abelian surfaces as formulated by Fité, Kedlaya, Rotger and Sutherland, using the potential automorphy theorems of Barnet-Lamb, Gee, Geraghty and Taylor.
  • Diagonal cycles and Euler systems II: the Birch and Swinnerton-Dyer conjecture for Hasse-Weil-Artin L-functions 

    Darmon, Henri; Rotger Cerdà, Víctor (2017-07-01)
    Article
    Accés restringit per política de l'editorial
    This article establishes new cases of the Birch and Swinnerton-Dyer conjecture in analytic rank 0, for elliptic curves over $ \mathbb{Q}$ viewed over the fields cut out by certain self-dual Artin representations of dimension ...
  • Constraints on the automorphism group of a curve 

    González Rovira, Josep (2017-01-01)
    Article
    Accés obert
    For a curve of genus > 1 defined over a finite field, we present a sufficient criterion for the non-existence of automorphisms of order a power of a rational prime. We show how this criterion can be used to determine the ...
  • Automorphism group of split Cartan modular curves 

    González Rovira, Josep (2016-08-01)
    Article

  • Functions and differentials on the non-split Cartan modular curve of level 11 

    Fernández González, Julio; González Rovira, Josep (2017-01-01)
    Article
    Accés obert
    The genus 4 modular curve Xns(11) attached to a non-split Cartan group of level 11 admits a model defined over Q. We compute generators for its function field in terms of Siegel modular functions. We also show that its ...
