Relative Chern characters for nilpotent ideals

Guillermo Cortiñas, Charles Weibel

If I is a nilpotent ideal in a $Q$ -algebra $A$ , Goodwillie defined two isomorphisms from $K_{*} (A, I)$ to negative cyclic homology, $H N_{*} (A, I)$ . One is the relative version o…

Bass' $N K$ groups and $c d h$ -fibrant Hochschild homology

G. Cortiñas, C. Haesemeyer, Mark E. Walker +1

The $K$ -theory of a polynomial ring $R [t]$ contains the $K$ -theory of $R$ as a summand. For $R$ commutative and containing $\Q$, we describe $K_{*} (R [t]) / K_{*} (R)$ in terms of Hochschi…
