+In view of Theorem \ref{thm:hochschild}, we have proved that $HH_*(k[t]) \cong C_*(\Sigma^\infty(S^1), k)$,
 and that the cyclic homology of $k[t]$ is related to the action of rotations
 on $C_*(\Sigma^\infty(S^1), k)$.
 \nn{probably should put a more precise statement about cyclic homology and $S^1$ actions in the Hochschild section}
