拟凝聚层的有限局部化分类

Classifying finite localizations of quasi-coherent sheaves

Grigory Garkusha

摘要:

给定一个拟紧拟分离的概型X,建立了Qcoh(X)中的张量局部化有限型子范畴与形式为$Y=\bigcup_{i\inΩ}Y_i$的所有子集$Y\subseteq X$的集合之间的双射,其中$X\setminus Y_i$是拟紧的,对所有$i\inΩ$都是开的.作为应用,构造了环空间(X,O_X)->(Spec(Qcoh(X)),O_{Qcoh(X)})的同构,其中$(Spec(Qcoh(X)),O_{Qcoh(X)})$是与张量局部化有限型子范畴格相联系的戴环空间.同时,建立了完备复形$\perf(X)$的张量厚子范畴与Qcoh(X)中有限型张量局部化子范畴之间的双射对应.

英文摘要:

Given a quasi-compact, quasi-separated scheme X, a bijection between the tensor localizing subcategories of finite type in Qcoh(X) and the set of all subsets $Y\subseteq X$ of the form $Y=\bigcup_{i\inΩ}Y_i$, with $X\setminus Y_i$ quasi-compact and open for all $i\inΩ$, is established. As an application, there is constructed an isomorphism of ringed spaces (X,O_X)-->(Spec(Qcoh(X)),O_{Qcoh(X)}), where $(Spec(Qcoh(X)),O_{Qcoh(X)})$ is a ringed space associated to the lattice of tensor localizing subcategories of finite type. Also, a bijective correspondence between the tensor thick subcategories of perfect complexes $\perf(X)$ and the tensor localizing subcategories of finite type in Qcoh(X) is established.
