极大奇点法的基本原理

Essentials of the method of maximal singularities

Aleksandr V. Pukhlikov

摘要:

一个一致的论述的论点和结构的方法的最大奇点,其目的是描述双有理iso/自同构的Fano品种和Fano纤维化。该方法的主要内容包括:N{\”o}ther-Fano不等式,极大圈,无穷大奇点,排斥和解扭.详细讨论了关键技术问题。我们还给出了Sarkisov定理的一个新的证明,它在思想上更接近于V. A. Iskovskikh和Yu. I. Manin的原始论证.

英文摘要:

A consistent exposition of the arguments and constructions of the method of maximal singularities, the aim of which is to describe birational iso/automorphisms of Fano varieties and Fano fibrations. The principal elements of the method are considered: N{\" o}ther-Fano inequality, maximal cycles, infinitely near maximal singularities, exclusion and untwisting. In a detailed way the crucial technical points are discussed. We also give a new version of the proof of Sarkisov theorem which is ideologically more close to the original arguments of V.A.Iskovskikh and Yu.I.Manin.
