Accumulation points on 3-fold canonical thresholds

Jheng-Jie Chen

We obtain that the nonzero accumulation points of the set of 3-fold canonical thresholds $\ct(X,S)$ are precisely $1/ k$ where $k \geq 2$ is an integer and $S$ is an effective integra…

On quint-canonical birationality of irregular threefolds

Jheng-Jie Chen, Jungkai Alfred Chen, Meng Chen +1

Let $X$ be a complex smooth projective threefold of general type. Assume $q (X) > 0$ . We show that the $m$ -canonical map of $X$ is birational for all $m \geq 5$ .

On Chern number inequality in dimension 3

Jheng-Jie Chen

We prove that if $X - - - > X^{+}$ is a threefold terminal flip, then $c_{1} (X) . c_{2} (X) \leq c_{1} (X^{+}) . c_{2} (X^{+})$ where $c_{1} (X)$ and $c_{2} (X)$ denote the Chern classes. This gives the affirmati…
