摘要

In this work, we describe the semigroup associated with a non-normal toric surface in \(\mathbb {C}^3\) C 3 and, consequently, its combinatorial structure. Using this combinatorial description and Newton polyhedra, we give a Whitney stratification for such surfaces, with fewer strata than the stratification induced by the torus action.
