Abstract:

The theory of complements was introduced by Shokurov when he investigated log flips on threefolds, which turns out to be a very powerful tool in birational geometry. For a Fano fibration from X to Z with X being $\epsilon$-log canonical, Shokurov proposed a conjecture on the boundedness of klt complements, i.e. the existence of klt n-complements for some bounded natural number n. When Z is a point or a curve, this conjecture was proved by Birkar. In this talk, I will discuss my recent work on the boundedness of klt complements on Fano fibrations over surfaces.
