The integrals of a holomorphic vector field Z defined in an open subset °U of C" are complex curves parametrized locally as the solutions of the differential equation They define a complex one-dimensional foliation J^z of °U with singularities at the zeros of Z.The purpose of this paper is to exhibit several topological invariants of these foliations near a singular point.Let Θ n be the ring of germs of holomorphic functions defined in some neighborhood of 0 G C w and let /(Z^ ,Z M ) be the ideal generated ...

In 1891, Poincaré started a series of three papers in which he tried to answer the following question (cf. [21–23]): "Is it possible to decide if an algebraic differential equation in two variables is algebraically integrable?" (in the sense that it has a rational first integral). More or less at the same time P. Painlevé asked the following question: "Is it possible to recognize the genus of the general solution of an algebraic differential equation in two variables which has a rational first integral?". ...

Let F be a codimension one singular holomorphic foliation on a compact complex manifold M. Assume that there exists a meromorphic vector field X on M generically transversal to F. Then, we prove that F is the meromorphic pull-back of an algebraic foliation on an algebraic manifold N, or F is transversely projective outside a compact hypersurface, improving our previous work (see version 1). Such a vector field insures the existence of a global meromorphic Godbillon-Vey sequence for the foliation ...

In this paper we study codimension one holomorphic foliations leaving invariant real analytic hypersurfaces. In particular, we prove that a germ of real analytic Levi-flat hypersurface with sufficiently ``small" singular set is given by the zeroes of the imaginary part of a holomorphic function.

In this paper, we give the explicit construction of certain components of the space of holomorphic foliations of codimension one, in complex projective spaces. These components are associated to some algebraic representations of the affine Lie algebra $\mathfrak{aff}(\mathbb{C})$ . Some of them, the so-called exceptional or Klein – Lie components, are rigid in the sense that all generic foliations in the component are equivalent (Example 1). In particular, we obtain rigid foliations of all degrees. Some ...

Let F be a codimension-one foliation on P n : for each point p ∈ P n we define J (F, p) as the order of the first non-zero jet j k p (ω) of a holomorphic 1form ω defining F at p.The singular set of F is sing(F) = { p ∈ P n | J (F, p) ≥ 1}.We prove (main Theorem 1.2) that a foliation F satisfying J (F, p) ≤ 1 for all p ∈ P n has a non-constant rational first integral.Using this fact we are able to prove that any foliation of degree-three on P n , with n ≥ 3, is either the pull-back of a foliation on P 2 , or has a transverse ...

Let us denote by X(n) the space of degree n G N foliations of the complex projective plane CP(2) which leave invariant the line at infinity.We prove that for each n > 2 there exists an open dense subset Rig(n) C X{n) such that any topologically trivial analytic deformation {J^t}t^ of an element FQ £ Rig(n), with J~t € ^{n}, for all t € D, is analytically trivial.This is an improvement of a remarkable result of Ilyashenko.Other generalizations of these results are given as well as a description of the class ...

This paper is devoted to the study of codimension two holomorphic foliations and distributions. We prove the stability of complete intersection of codimension two distributions and foliations in the local case. Conversely we show the existence of codimension two foliations which are not contained in any codimension one foliation. We study problems related to the singular locus and we classify homogeneous foliations of small degree.

Let $M$ be a compact complex manifold equipped with $n=\dim(M)$ meromorphic vector fields that are linearly independent at a generic point. The main theorem is the following. If $M$ is not bimeromorphic to an algebraic manifold, then any codimension one complex foliation $\mathcal F$ with a codimension $\ge2$ singular set is the meromorphic pull-back of an algebraic foliation on a lower dimensional algebraic manifold, or $\mathcal F$ is transversely projective outside a proper analytic subset. The two ingredients ...

Our main result says that the generic rank of the Baum–Bott map for foliations of degree is not the pull-back of a foliation of smaller degree. In Appendix A we show that the monodromy of the singular set of the universal foliation with very ample cotangent bundle is the full symmetric group.
