Singularities on toric fibrations
Caucher Birkar, Yifei Chen
In this paper we investigate singularities on toric fibrations. In this context we study a conjecture of Shokurov (a special case of which is due to M$^\rm{c}$Kernan) which roughly…
On singularities of threefold weighted blowups
Yifei Chen
We answer a question raised by Caucher Birkar for singularities of weighted blowups of , if .
On the moduli part of the Kawamata-Kodaira canonical bundle formula
Caucher Birkar, Yifei Chen
It is conjectured that the moduli b-divisor of the Kawamata-Kodaira canonical bundle formula associated to a klt-trivial fibration is semi-ample. In this paper, we sho…
Strong rational connectedness of toric varieties
Yifei Chen, Vyacheslav Shokurov
In this paper, we prove that: For any given finitely many distinct points and a closed subvariety of codimension in a complete toric variety over a uncou…
