Constancy regions of mixed multiplier ideals in two-dimensional local rings with rational singularities
Maria Alberich-Carramiñana, Josep Alvarez Montaner, Ferran Dachs-Cadefau
The aim of this paper is to study mixed multiplier ideals associated to a tuple of ideals in a two-dimensional local ring with a rational singularity. We are interested in the part…
