Resumo:
Secondary characteristic classes are cohomological invariants defined for foliations as a consequence of the integrability of foliations. We will make a brief introduction on these invariants, and then explain that the possibility of values of these cohomologial classes is finite when we fix a closed manifold M and consider all the foliations of M with transverse homogeneous structures associated to certain generalized flag manifold. This is a generalization of results of Brooks-Goldman and Heitsch in the case of transversely projective foliations. This talk is based on joint work with Jesús Antonio Álvarez López.

(This talk is done in Spanish.)
