Separatrices for real analytic vector fields in the plane

Eduardo Cabrera, Rogério Mol

Let be a germ of real analytic vector field at with an algebracally isolated singularity. We say that is a topological generalized curve if there are…

Holomorphic vector fields tangent to foliations in dimension three

Danúbia Junca, Rogério Mol

This article studies germs of holomorphic vector fields at the origin of C3 that are tangent to holomorphic foliations of codimension one. Two situations are considered. First, we…

On singular real analytic Levi-flat foliations

Arturo Fernández-Pérez, Rogério Mol, Rudy Rosas

A singular real analytic foliation of real codimension one on an -dimensional complex manifold is Levi-flat if each of its leaves is foliated by immersed compl…

Real Analytic Vector Fields with First Integral and Separatrices

Rogério Mol, Fernando Sanz Sánchez

We prove that a germ of analytic vector field at that possesses a non-constant analytic first integral has a real formal separatrix. We provide an example which…

Second type foliations of codimension one

Gilberto Cuzzuol, Rogério Mol

In this article, for holomorphic foliations of codimension one at , we define the family of second type foliations. This is formed by foliations having, in the…

Holomorphic foliations tangent to Levi-flat subsets

Jane Bretas, Arturo Fernández-Pérez, Rogério Mol

We study Segre varieties associated to Levi-flat subsets in complex manifolds and apply them to establish local and global results on the integration of tangent holomorphic foliati…
