Effective nonvanishing for weighted complete intersections of codimension two

Chen Jiang, Puyang Yu

We show Kawamata's effective nonvanishing conjecture (also known as the Ambro--Kawamata nonvanishing conjecture) holds for quasismooth weighted complete intersections of codimensio…

On the anti-canonical geometry of weak $Q$ -Fano threefolds, III

Chen Jiang, Yu Zou

For a terminal weak $Q$ -Fano $3$ -fold $X$ , we show that the $m$ -th anti-canonical map defined by $∣ - m K_{X} ∣$ is birational for all $m \geq 59$ .

An effective upper bound for anti-canonical volumes of canonical $Q$ -Fano threefolds

Chen Jiang, Yu Zou

We show that the anti-canonical volume of a canonical weak $Q$ -Fano $3$ -fold is at most $324$ .

Boundedness of threefolds of Fano type with Mori fibration structures

Chen Jiang

We show boundedness of $3$ -folds of $ε$ -Fano type with Mori fibration structures. The proof is based on the birational boundedness result in our previous work arXiv:1509.08722 comb…
