Abstract
Theorem 1.5. Let X be a minimal threefold of Kodaira dimension 1 and let 1r : X -+ C be associated Iitaka fibration. Then {1) either Kx · c2 = 0 and the smooth fibers are abelian or bi-elliptic surfaces or {2) there exists an f > 0, independent of X, such that Kx · c2 ~f > epsilon>0File in questo prodotto:
