Positive quadratic differential forms: topological equivalence through Newton Polyhedra

Marco Antonio Teixeira | Gutierrez, Carlos | Oliveira, Regilene

Keywords: positive quadratic differential forms | topological equivalence | Newton polyhedra | pair of foliations

We stablish conditions under which a positive quadratic differential form is topologically equivalent to its principal form defined by Newton polyhedra.The problem is carried out to study the simultaneous behavior of two foliations in the plane having a common point as a singularity.
