摘要
We regard the problem of classification for complex projective foliations with algebraic limit sets and prove the following: Let F be a holomorphic foliation by curves in the complex projective plane CP(2) having as limit set some singularities and an algebraic curve Lambda subset of CP(2). If the singularities sing F boolean AND Lambda are generic then either F is given by a closed rational 1-form or it is a rational pull-back gi a Riccati foliation R : p(x)dy - (a(x)y(2) + b(x)y)dx = 0, where Lambda corresponds to <(y = 0)over bar> boolean OR <(p(x) = 0)over bar>, on (C) over bar x (C) over bar. The proof is based on the solvability of the generalized holonomy groups associated to a reduction process of the singularities sing F boolean AND Lambda and the construction of an affine transverse structure for F outside an algebraic curve containing Lambda.
