Abstract: 导出射影化理论和导出blow-up理论是由姜清元和Jeroen Hekking正在发展的新理论，其可以看做是经典的Grothendieck射影化和blow-up理论在导出代数几何架构上的自然延伸🧑🏿🏫。在本次mini-course中🤥👩🏼⚖️，我将借助以上理论，提出一种拟光滑概型上的相对的广义消没理论👮🏿♀️👩🏽🚀。在时间允许的情况下🦵🏿，我会进一步讨论该理论在中岛箙多样体和量子圈群的Drinfeld表现中的应用。
The theories of derived projectivization and derived blow-ups are being developed by Qingyuan Jiang and Jeroen Hekking at the moment. They can be viewed as natural generalizations of the classical Grothendieck projectivization and blow-ups in the framework of derived algebraic geometry. In this mini-course, with the help of these theories, I will propose a generalized relative vanishing theory on quasi-smooth schemes. If time permits, I will discuss its applications to Nakajima quiver varieties and Drinfeld presentations of quantum loop groups.
