摘要

在本文中,我们引入了$S$-模块的一个副环版本。这些新对象被称为para-$S -模块。副环模和副链配合物产生对S -模的方式与循环模和混合配合物产生S -模的方式非常相似。更一般地说,para- S -模为我们提供了一个自然的框架来得到各种结构的副环模和副链配合物的类似物以及环模或混合配合物的等价结果。para-$S -模的基准不提供链复形,因此同构和拟同构的概念没有意义。建立了微分同调代数基本摄动引理的对- S -模和对链复的一些推广。这些推广为我们提供了将Hoschschild链配合物的变形缩回转化为对S模的变形缩回的一般方法。通过使用Kassel的思想,我们可以得到与对预环模相关的各种对预环模之间的比较结果,以及它们与Connes环链复合物之间的比较结果。这些比较结果使我们得到了对Connes周期算子的不同描述。这在周期循环同调中有一些应用。我们还描述了这些结果在循环上同中的对应关系。特别地,我们得到了将周期$(b, b)$-环转化为上同源周期循环环的显式方法。

Periodicity and cyclic homology. Para-$S$-modules and perturbation lemmas
In this paper, we introduce a paracyclic version of $S$-modules. These new objects are called para-$S$-modules. Paracyclic modules and parachain complexes give rise to para-$S$-modules much in the same way as cyclic modules and mixed complexes give rise to $S$-modules. More generally, para-$S$-modules provide us with a natural framework to get analogues for paracyclic modules and parachain complexes of various constructions and equivalence results for cyclic modules or mixed complexes. The datum of a para-$S$-module does not provide us with a chain complex, and so notions of homology and quasi-isomorphisms do not make sense. We establish some generalizations for para-$S$-modules and parachain complexes of the basic perturbation lemma of differential homological algebra. These generalizations provide us with general recipes for converting deformation retracts of Hoschschild chain complexes into deformation retracts of para-$S$-modules. By using ideas of Kassel this then allows us to get comparison results between the various para-$S$-modules associated with para-precyclic modules, and between them and Connes' cyclic chain complex. These comparison results lead us to alternative descriptions of Connes' periodicity operator. This has some applications in periodic cyclic homology. We also describe the counterparts of these results in cyclic cohomology. In particular, we obtain an explicit way to convert a periodic $(b,B)$-cocycle into a cohomologous periodic cyclic cocycle.
