  • Decomposition Spaces and Incidence (Co)Algebras . 

    Gálvez Carrillo, Maria Immaculada (Birkhäuser Verlag, 2015)
    Conference report

    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)
    Conference report

    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)
    Conference report
    Open Access
    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)
    Conference report
    Restricted access - publisher's policy
    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.
