Multiplier ideals of plane curve singularities via Newton polygons González Pérez, Pedro Daniel González Villa, Manuel Guzmán Durán, Carlos R. Robredo Buces, Miguel Geometría algebraica multiplier ideals jumping numbers plane curve singularities toroidal resolutions Matemáticas (Matemáticas) Geometria algebraica 12 Matemáticas 1201.01 Geometría Algebraica We give an effective method to determine the multiplier ideals and jumping numbers associated with a curve singularity C in a smooth surface. We characterize the multiplier ideals in terms of certain Newton polygons, generalizing a theorem of Howald, which holds when C is Newton non-degenerate with respect to some local coordinate system. The method uses toroidal embedded resolutions and generating sequences of families of valuations, and can be extended to some classes of higher dimensional hypersurface singularities.
