Blurred combinatorics in resolution of singularities: (a little) beyond the characteristic polytope
Helena Cobo, M. J. Soto, José M. Tornero
We introduce a variation of the well-known Newton-Hironaka polytope for algebroid hypersurfaces. This combinatorial object is a perturbed version of the original one, parametrized…

Combinatorics and their evolution in resolution of embedded algebroid surfaces
Helena Cobo, M. J. Soto, José M. Tornero
The seminal concept of characteristic polygon of an embedded algebroid surface, first developed by Hironaka, seems well suited for combinatorially (perhaps even effectively) tracki…
