摘要翻译:
设$V$是一般类型的复非奇异投影3重。我们将给出一个详细的分类,直到一篮子奇点在$v$的极小模型上。我们证明了$V$的$M$-规范映射对于所有$M\geq73$是双生的,规范卷$\text{Vol}(V)\geq{1/2660}$。当$\chi(\mathcal{O}_V)\leq1$时,我们的结果是$\text{Vol}(V)\geq{1/420}$,这是最优的。论文还包括了其他有效的结果。

英文摘要:
Let $V$ be a complex nonsingular projective 3-fold of general type. We shall give a detailed classification up to baskets of singularities on a minimal model of $V$. We show that the $m$-canonical map of $V$ is birational for all $m\geq 73$ and that the canonical volume $\text{Vol}(V)\geq {1/2660}$. When $\chi(\mathcal{O}_V)\leq 1$, our result is $\text{Vol}(V)\geq {1/420}$, which is optimal. Other effective results are also included in the paper.
