| contents | We study codimension $q \geq 2$ holomorphic foliations defined in a neighborhood of a point $P$ of a complex manifold that are completely integrable, i.e. with $q$ independent meromorphic first integrals. We show that either $P$ is a regular point, a non-isolated singularity or there are infinitely many invariant analytic varieties through $P$ of the same dimension as the foliation, the so called separatrices. Moreover, we see that this phenomenon is of topological nature.
Indeed, we introduce topological counterparts of completely integrable local holomorphic foliations and tools, specially the concept of total holonomy group, to build holomorphic first integrals if they have isolated separatrices. As a result, we provide a topological characterization of completely integrable non-degenerated elementary isolated singularities of vector fields with an isolated separatrix. |
