  • Decomposition Spaces and Incidence (Co)Algebras . 

    Gálvez Carrillo, Maria Immaculada (Birkhäuser Verlag, 2015)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    Decomposition spaces are simplicial 88 -groupoids with an exactness property giving coherent associativity of its objective incidence (co)algebra. Our theory encompasses the Connes–Kreimer algebra, (derived) Hall algebras ...
  • Lyubeznik numbers of local rings and linear strands of graded ideals 

    Álvarez Montaner, Josep (Springer, 2016)
    Text en actes de congrés
    Accés restringit per política de l'editorial
    We report recent work on the study of Lyubeznik numbers and their relation to invariants coming from the study of linear strands of free resolutions.
  • Poisson geometry and normal forms: a guided tour through examples 

    Miranda Galcerán, Eva (2015)
    Text en actes de congrés
    Accés obert
    There are no special prerequisites to follow this minicourse except for basic differential geometry. Poisson manifolds constitute a natural generalization of Symplectic manifolds. Many problems in mechanics turn out to ...
  • Computing jumping numbers and multiplier ideals in two-dimensional regular local rings 

    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.
