On the pluricanonical map of projective 3-folds of general type with $P_{3} \geq 2$

Yong Hu, Jianshi Yan

We prove that for all nonsingular projective 3-folds of general type with third plurigenus $P_{3} \geq 2$ , the pluricanonical map $I ¨ _{m}$ is birational onto its image for all $m \geq…

On the bicanonical map of algebraic threefolds of general type

Meng Chen, Chen Jiang, Jianshi Yan

We answer an open problem of the first author and Zhang (see Open Problem 6.4 (3) in Math. Z. 258 (2008), 565-585) and prove that, for any nonsingular projective $3$ -fold of genera…
