      Alberich Carramiñana, Maria; Álvarez Montaner, Josep; Dachs Cadefau, Ferran (Universitat de Barcelona. Edicions i Publicacions, 2014)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      We give a new algorithm that computes the jumping numbers with their multiplicities and multiplier ideals of any ideal in a regular two-dimensional local ring.
    • Constancy regions of mixed multiplier ideals in two-dimensional local rings with rational singularities 

      Alberich Carramiñana, Maria; Álvarez Montaner, Josep; Dachs Cadefau, Ferran (WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim, 2018)
      Article
      Accés obert
      The aim of this paper is to study mixed multiplier ideals associated with a tuple of ideals in a two-dimensional local ring with a rational singularity. We are interested in the partition of the real positive orthant given ...

    • Multiplicities of jumping points for mixed multiplier ideals 

      Alberich Carramiñana, Maria; Álvarez Montaner, Josep; Dachs Cadefau, Ferran; González Alonso, Víctor (Springer, 2019-01-01)
      Article
      Accés obert
      In this paper we make a systematic study of the multiplicity of the jumping points associated to the mixed multiplier ideals of a family of ideals in a complex surface with rational singularities. In particular we study ...

    • Multiplier ideals in two-dimensional local rings with rational singularities 

      Dachs Cadefau, Ferran (Universitat Politècnica de Catalunya, 2016-06-13)
      Tesi
      Accés obert
      Realitzat a/amb:   Katholieke Universiteit te Leuven
      The aim of this memoir is to study multiplier ideals in two-dimensional local rings having at worst rational singularities. We also want to extend this study to the case of mixed multiplier ideals. The main achievements ...
    • Multiplier ideals in two-dimensional local rings with rational singularities 

      Alberich Carramiñana, Maria; Álvarez Montaner, Josep; Dachs Cadefau, Ferran (2016)
      Article
      Accés restringit per política de l'editorial
      The aim of this paper is to study jumping numbers and multiplier ideals of any ideal in a two-dimensional local ring with a rational singularity. In particular we reveal which information encoded in a multiplier ideal ...
    • Multiplier ideals of plane curves 

      Dachs Cadefau, Ferran (Universitat Politècnica de Catalunya, 2012-10)
      Projecte Final de Màster Oficial
      Accés restringit per decisió de l'autor
      Multiplier ideals and their corresponding jumping numbers have been revealed as a fundamental tool to measure the singularity of plane curves. There are approaches to these objects from both Commutative Algebra and Algebraic ...
    • Poicaré series for mixed multiplier ideals 

      Alberich Carramiñana, Maria; Álvarez Montaner, Josep; Dachs Cadefau, Ferran; González Alonso, Víctor (2018)
      Article
      Accés obert
      We present a generalization of the Poincaré series to the case of mixed multiplier ideals. For that, we will recall some results about how we can compute the jumping walls associated to a mixed multiplier ideal and introduce ...
    • Poincare series of multiplier ideals in two-dimensional local rings with rational singularities 

      Alberich Carramiñana, Maria; Álvarez Montaner, Josep; Dachs Cadefau, Ferran; González Alonso, Víctor (2017-01-02)
      Article
      Accés obert
      We study the multiplicity of the jumping numbers of an mm-primary ideal a in a two-dimensional local ring with a rational singularity. The formula we provide for the multiplicities leads to a very simple and efficient ...
