摘要

我们对皮卡德秩 2 的光滑射影变种进行了分类,这些变种有两种沿不同维度的光滑子变种的射影空间膨胀结构。这给出了所谓四立方克雷莫纳变换的特征。

Varieties with two smooth blow up structures
We classify smooth projective varieties of Picard rank 2 which has two structures of blow-up of projective space along smooth subvarieties of different dimensions. This gives a characterization of the so called quadro-cubic Cremona transformation.
