摘要： In this talk, we shall study canonical bundle formula in positive characteristics. Compared with Kodaira's canonical bundle formula in char 0, and Bombieri-Mumford canonical bundle formula in char p, we want to derive a similar formula for Kodaira-Kawamata's canonical bundle formula for elliptic fibration. As well, semi-positivity for a fibration will be discussed. This is a joint work with Yi Gu.
