| This paper is devoted to describe the structure of singular codimension one foliations with numerically trivial canonical bundle on projective manifolds. To achieve this goal we study the reduction modulo p of foliations, describe the structure of first integrals of (semi-)stable foliations with (negative) zero canonical bundle, establish a criterium for uniruledness of projective manifolds, and investigate the deformation of free morphisms along foliations. This paper also contains a classification of the irreducible components of the space of foliations with KF ≤ 0 on Fano 3-folds with rank one Picard group, and new information about the structure of codimension one foliations on P^n of degree smaller than or equal to 2n − 3. |
