  • Effective computation of base points of two-dimensional ideals 

    Blanco Fernández, Guillem (Universitat Politècnica de Catalunya, 2015-10)
    Master thesis
    Open Access
    This works focus on computational aspects of the theory of singularities of plane algebraic curves. We show how to use the Puiseux factorization of a curve, computed through the Newton-Puiseux algorithm, to study the ...

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

    Dachs Cadefau, Ferran (Universitat Politècnica de Catalunya, 2016-06-13)
    Doctoral thesis
    Open Access
    Covenantee:  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 of plane curves 

    Dachs Cadefau, Ferran (Universitat Politècnica de Catalunya, 2012-10)
    Master thesis
    Restricted access - author's decision
    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 ...
  • Scheme of pairs of matrices with vanishing commutator 

    Llopis Vidal, Bartomeu (Universitat Politècnica de Catalunya, 2019-05-27)
    Bachelor thesis

    Let $X$ be smooth projective curve of genus $g$. Let $R(g,n)$ be $Hom(\pi_1(X),GL_n(C)$ with the natural affine scheme structure. If $g>1$, it is known that the representation space $R(g,n)$ is an irreducible reduced normal ...
