Flops and about: a guide
摘要：
层错出现在辛簇的双有理几何中，如幂零轨道和层的模空间的分解。奇怪的是，在由这种失败相关的变种之间构造派生等价关系，与表示论和纽结同调有关。在本文中，我们将讨论如何构建这样的等价，解释这样做的主要工具（类别李代数行动）和评论各种相关的主题。
英文摘要：
Stratified flops show up in the birational geometry of symplectic varieties such as resolutions of nilpotent orbits and moduli spaces of sheaves. Constructing derived equivalences between varieties related by such flops is, strangely enough, related to areas in representation theory and knot homology. In this paper we discuss how to construct such equivalences, explain the main tool for doing this (categorical Lie algebra actions) and comment on various related topics.
