仿射同调$3$ -胞紧化为具有平凡log典范除子的射影$3$ -空间的爆破

Compactifications of affine homology $3$-cells into blow-ups of the projective $3$-space with trivial log canonical divisors

Masaru Nagaoka

摘要:

本文将仿射同调$3$ -胞腔的紧化分类为射影$3$ -空间沿平滑曲线的爆破,使得对数典范除子是线性平凡的。因此,我们证明了每个嵌入的仿射$3$ -折叠同构于仿射$3$ -空间,除了一个例子。

英文摘要:

In this paper we classify all the compactifications of affine homology $3$-cells into the blow-ups of the projective $3$-space along smooth curves such that the log canonical divisors are linearly trivial. As a result, we prove that each embedded affine $3$-fold is isomorphic to the affine $3$-space except one example.
