Abstract
We show that if is an algebraically integrable foliation on a -factorial normal projective variety , are -divisors on with ample such that is foliated dlt and is nef, then is semiample. We also provide some applications of this and related results such as contraction theorem for F-dlt pairs and a special case of the b-semiampleness conjecture.
