我们提出了一个类似的有界衍生类的增广环谱,定义在诺特规范化的概念。在许多情况下,我们证明了这个类别与所选择的归一化无关。在此基础上,我们定义了度量正则性和共正则性失效的奇异性和余奇异性范畴,并证明了它们是BGG对应形式的Koszul对偶。感兴趣的例子包括Koszul代数和Ginzburg DG-代数,有限群的C(B G)(或具有可定向伴随表示的紧李群),有理同伦理论中的上链和色同伦理论中的各种例子。
We propose an analogue of the bounded derived category for an augmented ring spectrum, defined in terms of a notion of Noether normalization. In many cases we show this category is independent of the chosen normalization. Based on this, we define the singularity and cosingularity categories measuring the failure of regularity and coregularity and prove they are Koszul dual in the style of the BGG correspondence. Examples of interest include Koszul algebras and Ginzburg DG-algebras, C⁎(B G) for finite groups (or for compact Lie groups with orientable adjoint representation), cochains in rational homotopy theory and various examples from chromatic homotopy theory.
