本文介绍了模 varieties 和墙穿越理论,涵盖过去几年的发展,包括工具和技术及新示例的应用。

摘要:

过去十年中,关于 varieties 的模空间理论取得了重大进展,基本上解决了 log 可极化 slc 对的模空间和 K-多稳 log Fano 对的模空间的构造问题。在这些对 (X, D) 的模空间构造之后,自然会问当 D 的系数被扰动时,模空间如何变化。这种现象称为墙穿越,其理论在过去五年中在几个重要情况下得到了发展。本文是一篇半综述性质的文章,介绍了 varieties 的模空间和墙穿越理论,涵盖了过去几年中发展的一些理论部分。它还介绍了用于显式计算和示例中的工具和技术,并在新示例中加以应用。

英文摘要:

There have been major developments in the theory of moduli of varieties in the past decade, essentially settling the construction of moduli spaces of log canonically polarized slc pairs and moduli spaces of K-polystable log Fano pairs. Given the construction of these moduli spaces of pairs $(X, D)$, it is natural to ask how the moduli spaces vary as the coefficients of $D$ are perturbed. This phenomenon is known as wall crossing, the theory of which has been developed in several important cases in the past five years. This semi-expository article is an introduction to moduli of varieties and wall crossing, capturing a portion of the theory developed in the past several years. It also introduces tools and techniques used in explicit computations and examples, applying them in new examples.
