On the boundedness of elliptic Calabi-Yau 4-folds
Stefano Filipazzi, Fulin Xu
In this work, we settle the boundedness of a vast class of elliptic Calabi-Yau 4-folds. In particular, we show that any elliptic Calabi-Yau 4-fold that is not crepant to the quotie…

On finiteness of fiber space structures of klt Calabi-Yau pairs in dimension 3
Fulin Xu
We prove that for a fixed klt Calabi-Yau pair of dimension , the set of fiber space structures of is finite up to .

On the cone conjecture for certain pairs of dimension at most 4
Fulin Xu
In this paper, by running MMP and considering the anti-canonical fibration, we prove the Morrison-Kawamata cone conjecture for klt Calabi-Yau pairs such that is at…
