    We construct a Koszul complex in the category of left skew polynomial rings associated with a flat endomorphism that provides a finite free resolution of an ideal generated by a Koszul regular sequence
  • Emmy Noether i l’àlgebra commutativa 

    Zarzuela Armengou, Santiago (2009-02-18)
    Audiovisual
    Open Access
    Emmy Noether representa un punt d’inflexió fonamental en el desenvolupament de l’Àlgebra Commutativa. Per una banda, en ella conflueixen algunes de les línies evolutives prèvies més importants. Per altra, a partir del seu ...
  • Frobenius and Cartier algebras of Stanley-Reisner rings 

    Álvarez Montaner, Josep; Boix, Alberto F.; Zarzuela Armengou, Santiago (2011-09)
    External research report
    Open Access
    We study the generation of the Frobenius algebra of the injective hull of a complete Stanley-Reisner ring over a field with positive characteristic. In particular, by extending the ideas used by M. Katzman to give a ...

  • Linearization of local cohomology modules 

    Álvarez Montaner, Josep; Zarzuela Armengou, Santiago (American Mathematical Society, 2003)
    Part of book or chapter of book
    Open Access
    The aim of this work is to describe the linear structure of regular holonomic $\mathcal D$-modules with support a normal crossing with variation zero introduced in [Local cohomology, arrangements of subspaces and monomial ...
