Resolving singularities of curves with one toric morphism

Abstract

We give an explicit positive answer, in the case of reduced curve singularities, to a question of B. Teissier about the existence of a toric embedded resolution after reembedding. In the case of a curve singularity (C,O)(C,O) contained in a non singular surface SS such a reembedding may be defined in terms of a sequence of maximal contact curves of the minimal embedded resolution of CC. We prove that there exists a toric modification, after reembedding, which provides an embedded resolution of CC. We use properties of the semivaluation space of SS at OO to describe how the dual graph of the minimal embedded resolution of CC may be seen on the local tropicalization of SS associated to this reembedding.
