摘要

我们定义了轨迹范畴的共上同调，并证明了它通过一个长精确序列与对应的\(({\mathcal {S}}\!,\!\mathcal {O})\) -上同调相关。在温和的假设下，共上同调与\(({\mathcal {S}}\!,\!\mathcal {O})\) -上同调重合，直至重合，产生了后者的代数描述。我们还专门研究轨道类别是2-groupoid的情况。

Comonad cohomology of track categories

We define a comonad cohomology of track categories, and show that it is related via a long exact sequence to the corresponding \(({\mathcal {S}}\!,\!\mathcal {O})\)-cohomology. Under mild hypotheses, the comonad cohomology coincides, up to reindexing, with the \(({\mathcal {S}}\!,\!\mathcal {O})\)-cohomology, yielding an algebraic description of the latter. We also specialize to the case where the track category is a 2-groupoid.
