In this word, we did a detailed study of the Baum-Bott s theorem in two situations. To do this, we examine this theorem in [2] and its proof given by S. S. Chern using methods of differential geometry, in which case the non-degenerated singularities for one-dimensional holomorphic foliation.Then use the article [31] of M. Soares, where he retraces the Chern s proof with a slight change, thus eliminating the possibility of non-degenerated. The result of great importance because it is applied to meromorphic vector fields, which are abundant and generate one-dimensional singular holomorphic foliations in compact manifolds. As a way to apply this result, we deal with the problem of Poincare in [28] to limit the degree of an invariant curve depending on the degree of the foliation. This problem was motivated by the work of Darboux with respect to algebraic integrability foliations in [13]. We gathered the results of Cerveau and Lins Neto in [12] and also M.Carnicer in [9] about the problem of Poincare, that were introduced about 100 years later the work of Poincaré. Finally we also explored the contribution of M. Soares to this problem in [32].
