Boundaries of the dual Newton polyhedron may describe the singularity

Abstract: We are dealing with a hypersurface $X\subset\mathbb{C}^3$ having non-isolated singularities.We construct an embedded toric resolution of $X$ using some specific vectors in its dual Newton polyhedron. To do this, we first define the profile of a full dimensional cone and we establish a relation between the jet vectors and the integer points in the profile.

This is a part of the joint work with C. Plénat and M. Tosun.
