In this article we characterize the foliations that have the same Newton polygon that their union of formal separatrices, they are the foliations called of the second type. In the case of cuspidal foliations studied by Loray [Lo], we precise this cha

In this article we study the analytic classification of certain types of quasi-homogeneous cuspidal holomorphic foliations in $(\CC^3,{\bf 0})$ via the essential holonomy defined over one of the components of the exceptional divisor that appears in t

In this paper, we will construct a pre-normal form for germs of codimension one holomorphic foliation having a particular type of separatrix, of cuspidal type. We will also give a sufficient condition, in the quasi-homogeneous, three-dimensional case

The polynomial maps whose Jacobian determinant is equal to 1 are called Keller maps. The Keller Jacobian conjecture claims that every Kellermap is injective. This conjecture is true for polynomials whose degree is less than or equal to two. In this p

En el ICM (Intemational Congress of Mathematicians) de 1900, Hilbert presenta 23 problemas que establecieron el curso de gran parte de las investigaciones matemáticas del siglo XX. El 21° problema es la existencia de ecuaciones diferenciales lineal
