摘 要: Kodaira's canonical bundle formula applies to fibrations with general fiber of Kodaira dimension zero. I will present a generalization of this formula to the case when the Kodaira dimension of the general fiber is non-negative, due to Shokurov (part of it conjectural). We show in the end that the moduli part is semipositive, modulo standard conjectures. Based on joint work with Cascini, Shokurov, Spicer.
