    This is an expository survey on the theory of Bernstein-Sato polynomials with special emphasis in its recent developments and its importance in commutative algebra
  • When is a complete ideal in a rational surface singularity a multiplier ideal? 

    Alberich Carramiñana, Maria; Álvarez Montaner, Josep; González Alonso, Víctor (Springer-Birkhäuser, 2021)
    Part of book or chapter of book

    This is an extended abstract with some of the results that will appear in the forthcoming paper [1] in which we characterize when a given complete ideal in a two-dimensional local ring with a rational singularity can be ...
  • Developable surfaces with prescribed boundary 

    Alberich Carramiñana, Maria; Amorós Torrent, Jaume; Coltraro Ianniello, Franco (Springer-Birkhäuser, 2021)
    Part of book or chapter of book
    Open Access
    It is proved that a generic simple, closed, piecewise regular curve in space can be the boundary of only infinitely many developable surfaces with nonvanishing mean curvature. The relevance of this result in the context ...
  • Rank conditions on phylogenetic networks 

    Casanellas Rius, Marta; Fernández Sánchez, Jesús (Birkhäuser, 2021)
    Part of book or chapter of book
    Restricted access - publisher's policy
    Less rigid than phylogenetic trees, phylogenetic networks allow the description of a wider range of evolutionary events. In this note, we explain how to extend the rank invariants from phylogenetic trees to phylogenetic ...
  • Reeb embeddings and universality of Euler flows 

    Cardona Aguilar, Robert; Miranda Galcerán, Eva; Peralta Salas, Daniel; Presas, Francisco (Springer, 2021)
    Part of book or chapter of book
    Open Access
    We use a new geometrical approach to the universality of Euler flows. By proving flexibility results on embeddings for Reeb flows in contact topology, we deduce some new universal properties for Euler flows. As a byproduct, ...
  • Monodromía geométrica en familias de curvas de género 4 

    Amorós Torrent, Jaume; Berna Sepúlveda, Isabel (2012)
    Part of book or chapter of book
    Open Access
    The geometric mono dromy of a family of complex pro jective curves is equiv- alent to the mono dromy in the fundamental group of the b ers. When the family is one of branched covers of the pro jective line this mono ...
  • Lyubeznik numbers of local rings and linear strands of graded ideals 

    Álvarez Montaner, Josep (Springer, 2016)
    Part of book or chapter of book
    Restricted access - publisher's policy
    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
  • Some properties of multisymplectic manifolds 

    Román Roy, Narciso (Springer, 2019-10-01)
    Part of book or chapter of book
    Restricted access - publisher's policy
    This lecture is devoted to review some of the main properties of multisymplectic geometry. In particular, after reminding the standard definition of multisymplectic manifold, we introduce its characteristic submanifolds, ...
