    • Bernstein's inequality and holonomicity for certain singular rings 

      Álvarez Montaner, Josep; Jeffries, Jack; Núñez-Betancourt, Luis; Hernández, Daniel J.; Teixeira, Pedro; Witt, Emily E. (2021)
      Report de recerca
      Accés obert
      In this manuscript we prove the Bernstein inequality and develop the theory of holonomic D-modules for rings of invariants of finite groups in characteristic zero, and for strongly F-regular finitely generated graded ...

    • Bernstein-Sato functional equations, v -filtrations, and multiplier ideals of direct summands 

      Álvarez Montaner, Josep; Hernández, Daniel J.; Jeffries, Jack; Núñez-Betancourt, Luis; Teixeira, Pedro; Witt, Emily E. (2021-01-01)
      Article
      Accés obert
      This paper investigates the existence and properties of a Bernstein– Sato functional equation in nonregular settings. In particular, we construct D-modules in which such formal equations can be studied. The existence of ...

    • Bernstein-Sato polynomials in commutative algebra 

      Álvarez Montaner, Josep; Jeffries, Jack; Núñez-Betancourt, Luis (Springer Nature, 2022-02-23)
      Capítol de llibre
      Accés restringit per política de l'editorial
      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

    • D-modules, Bernstein-Sato polynomials and F-invariants of direct summands 

      Álvarez Montaner, Josep; Huneke, Craig; Núñez-Betancourt, Luis (2017-12-01)
      Article
      Accés obert
      We study the structure of D -modules over a ring R which is a direct sum- mand of a polynomial or a power series ring S with coefficients over a field. We relate properties of D -modules over R to D -modules over S . We ...

    • Poincaré series of multiplier and test ideals 

      Álvarez Montaner, Josep; Núñez-Betancourt, Luis (2021)
      Report de recerca
      Accés obert
      We prove the rationality of the Poincaré series of multiplier ideals in any dimension and thus extending the main results for surfaces of Galindo and Monserrat and Alberich-Carramiñana et al. Our results also hold for ...
