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 …

Historically cyclic cohomology was approached from two directions. In one, Connes
developed cyclic cohomology as a noncommutative analogue of de Rham cohomology …

The Jaffe-Lesniewski-Osterwalder (JLO) character is a homomorphism from K-homology to
entire cyclic cohomology. This paper extends the domain of the JLO character to include …

We give a survey of cyclic homology/cohomology theory including a detailed discussion of
cyclic theories for various classes of topological algebras. We show how to associate cyclic …

...- H,(A, A)-HC,(A)--S-, HC, p,(A)-H,-,(A, A)-..., relating cyclic and Hochschild homology, one
can see that any formula for HC,(A@ A') will not only involve HC,(A) and HC,(A'), but also the …

Based on the ideas of Cuntz and Quillen, we give a simple construction of cyclic homology
of unital algebras in terms of the noncommutative de Rham complex and a certain …

We define a noncommutative analogue of invariant de Rham cohomology. More precisely,
for a triple $(A,\mathcal {H}, M) $ consisting of a Hopf algebra $\mathcal {H} $, an $\mathcal …

In this course, we will study certain invariants of associative algebras, called cyclic
homology. These invariants were independently introduced by Alain Connes and Boris …

In his foundational paper on cyclic cohomology [Co], A. Connes introduced, besides the
ordinary cyclic cohomology, also the periodic theory. This was motivated, in the first place …
