向量空间的双复形经常出现在代数和几何中。在第2节中,我们解释如何通过其不可分解的和项来考虑双复形的谱序列中的箭头。多元复合物似乎更为罕见。在本文的第三节中,我们通过在三复形的稳定范畴上的作用,重新考虑了一个著名的忠实范畴辫群作用。
Bicomplexes of vector spaces frequently appear throughout algebra and geometry. In Section 2 we explain how to think about the arrows in the spectral sequence of a bicomplex via its indecomposable summands. Polycomplexes seem to be much more rare. In Section 3 of this paper we rethink a well-known faithful categorical braid group action via an action on the stable category of tricomplexes.
