Description
It is a local version of a conjecture of Brunella which says that a codimension 1 foliation in the projective three-dimensional space P^3 either has an invariant algebraic surface or each leaf is sub-foliated by a one-dimensional foliation. In this local take, we have the following "local conjecture": a germ of holomorphic codimension 1 foliation in C^3,0 either possesses a germ of analytic invariant surface, or there exists a neighborhood of the origin wherein each leaf contains a germ of analytic curve. We give a positive answer to this local conjecture for certain types of foliations.
