摘要翻译:
在交换诺以太环R上的模的导出范畴上,我们利用规范(R)上的支集减少滤子的方法,对自鸣得意生成的T-结构进行了分类。如果对于Z中的任意整数i,集\phi(i)包含\phi(i+1)中每个点的所有非中介推广,则按支持度递减过滤\phi:z->Spec(R)满足弱表亲条件。D^b_fg(R)(等价地,在D^-_fg(R))上的每一个T结构都是由D(R)上自鸣得意地生成的T结构所诱导的,这些T结构的支持过滤满足弱表亲条件。如果环R具有对偶复形,我们证明了它们正是D^B_FG(R)上的T-结构。更一般地,如果R具有逐点对偶复形,我们将D_fg(R)上所有紧致生成的T-结构分类。

英文摘要:
We classify complactly generated t-structures on the derived category of modules over a commutative Noetherian ring R in terms of decreasing filtrations by supports on Spec(R). A decreasing filtration by supports \phi : Z -> Spec(R) satisfies the weak Cousin condition if for any integer i \in Z, the set \phi(i) contains all the inmediate generalizations of each point in \phi(i+1). Every t-structure on D^b_fg(R) (equivalently, on D^-_fg(R)) is induced by complactly generated t-structures on D(R) whose associated filtrations by supports satisfy the weak Cousin condition. If the ring R has dualizing complex we prove that these are exactly the t-structures on D^b_fg(R). More generally, if R has a pointwise dualizing complex we classify all compactly generated t-structures on D_fg(R).
