关于P^3的极小形式分解的Cremona变换

On Cremona Transformations of P^3 which factorize in a minimal form

Ivan Pan

摘要:

我们考虑3维复射影空间的Cremona变换,它分解为至多两个II型基本链的乘积,没有小的收缩,连接两个Fano 3-folds。我们表明,基本上有八类这样的变换,我们给这些类中的每一个元素的几何描述。

英文摘要:

We consider Cremona transformations of the complex projective space of dimension 3 which factorize as a product of at most two elementary links of type II, without small contractions, connecting two Fano 3-folds. We show that there are essentially eight classes of such transformations and we give a geometric description of elements in each of these classes.
