Excision in Cyclic Homology Theories, by Michael Puschnigg
In this paper we present a modified version of the proof of excision in
bivariant periodic cyclic cohomology by J. Cuntz and D. Quillen. This
modified proof has the advantage of working also in the framework of entire
cyclic and asymptotic cyclic cohomology or more general in the framework of
cyclic and local cyclic cohomology of algebras with supports. As
applications we derive an estimate for the behaviour of the dimension of a
cyclic cocycle under the Cuntz-Quillen boundary map, calculate the entire
cyclic cohomology of the algebra of smooth functions on a compact manifold
and construct a bivariant Chern-Connes character on Kasparov's bivariant
K-theory.
