Abstract

In this paper we consider the question of bounding the degree of an divisor DD invariant by a \F\F holomorphic foliation, without rational first integral, on smooth algebraic variety XX in terms of degree of \F\F and some invariants of DD and XX. Particularly, if \F\F is a foliation of degree dd on PC2\mathbb{P}_{\mathbb{C}}^2, whose the number of invariants curves is greater that (k+2k){k+2\choose k}, we show that there exist a number M(d,k)\mathcal{M}(d,k) such that if k>M(d,k),k>\mathcal{M}(d,k), then \F\F admits a rational first integral of degree k\leq k. Moreover, there exist a number G(d,k)\mathscr{G}(d,k), such that if \F\F has an algebraic solution of degree kk and genus smaller than G(d,k)\mathscr{G}(d,k), then it has a rational first integral of degree k\leq k.
