Abstract:

Given a homology theory ${H_*}(A)$ on rings, based on a natural chain complex, one can form a new theory $H_*^h(A)$ which is universal with respect to the homotopy property ${H_*}(A) \simeq {H_*}(A[t])$. We show that the homotopy theories $HH_*^h$ and $HC_*^h$ associated to Hochschild and cyclic homology are both zero. On the other hand, if $HC_*^ -$ denotes Goodwillie’s variant of cyclic homology, and $A$ contains a field of characteristic 0, we show that $(H{C^ - })_*^hA$ is Connes’ periodic cyclic homology $H{P_*}(A)$.
