正熵伪自同构的正则化
Regularizations of positive entropy pseudo-automorphisms
摘要：
研究了三重正熵双有理自同构。我们确定了一些条件，这意味着这样的自同构是非正则化的。我们表明，这一标准适用于一个正熵双有理自同构的$\mathbb{P}^3$ J. Blanc构造的例子，从而表明，对于一般的参数选择，它是nonregularizable。此外，我们建立了一个标准，证明在这个例子中的自同构不保持纤维化的结构在一个表面上。
英文摘要：
We study positive entropy birational automorphisms of threefolds. We identify some conditions which imply that such an automorphism is non-regularizable. We show that this criterion applies in the example of a positive entropy birational automorphism of $\mathbb{P}^3$ constructed by J. Blanc, thus showing that for a general choice of parameters it is non-regularizable. Additionally, we establish a criterion which proves that the automorphism in this example does not preserve a structure of a fibration over a surface.
