On some local cohomology spectral sequences
(2020)
Article
Accés obertWe introduce a formalism to produce several families of spectral sequences involving the derived functors of the limit and colimit functors over a finite partially ordered set. The 1st type of spectral sequences involves ... -
Operations with regular holonomic D-modules with support a normal crossing
(2003)
Article
Accés obertThe aim of this work is to describe some operations in the category of regular holonomic $\cD$-modules with support a normal crossing and variation zero introduced in [J.Alvarez Montaner, R.Garcia Lopez and S.Zarzuela, ... -
Poicaré series for mixed multiplier ideals
(2018)
Article
Accés obertWe present a generalization of the Poincaré series to the case of mixed multiplier ideals. For that, we will recall some results about how we can compute the jumping walls associated to a mixed multiplier ideal and introduce ... -
Poincare series of multiplier ideals in two-dimensional local rings with rational singularities
(2017-01-02)
Article
Accés obertWe study the multiplicity of the jumping numbers of an mm-primary ideal a in a two-dimensional local ring with a rational singularity. The formula we provide for the multiplicities leads to a very simple and efficient ... -
Poincaré series of multiplier and test ideals
(2021)
Report de recerca
Accés obertWe 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 ... -
Poincaré series of multiplier and test ideals
(2022-04-29)
Article
Accés obertWe prove the rationality of the Poincaré series of multiplier ideals in any dimension thus extending the main results for surfaces of Galindo and Monserrat and Alberich-Carramiñana et al. Our results also hold for Poincaré ... -
Pruned cellular free resolutions of monomial ideals
(2020-01-01)
Article
Accés obertUsing discrete Morse theory, we give an algorithm that prunes the excess of information in the Taylor resolution and constructs a new cellular free resolution for an arbitrary monomial ideal. The pruned resolution is not ... -
Some numerical invariants of local rings
(2002)
Article
Accés obertLet $R$ be a formal power series ring over a field of characteristic zero and $I\subseteq R$ be any ideal. The aim of this work is to introduce some numerical invariants of the local rings $R/I$ by using theory of ... -
Three lectures on local cohomology modules supported on monomial ideals
(2012-09)
Report de recerca
Accés obertThese notes are an extended version of a set of lectures given at ”MONICA: MONomial Ideals, Computations and Applications”, at the CIEM, Castro Urdiales (Cantabria, Spain) in July 2011. The goal of these lectures is to ... -
When is a complete ideal in a rational surface singularity a multiplier ideal?
(Springer-Birkhäuser, 2021)
Capítol de llibre
Accés restringit per política de l'editorialThis 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 ...
