The cyclic homology and K-theory of certain adelic crossed products
Ralf Meyer
The multiplicative group of a global field acts on its adele ring by multiplication. We consider the crossed product algebra of the resulting action on the space of Schwartz functi…
A characterization of the Dirac Dual Dirac Method
Heath Emerson, Ralf Meyer
Let G be a discrete, torsion free group with a finite dimensional classifying space BG. We show that the existence of a gamma-element for such G is a metric, that is, coarse, invar…
Comparisons between periodic, analytic and local cyclic cohomology
Ralf Meyer
We compute periodic, analytic and local cyclic cohomology for convolution algebras of compact Lie groups in order to exhibit differences between these theories. A surprising result…
Analytic cyclic cohomology
Ralf Meyer
We prove excision in entire and periodic cyclic cohomology and construct a Chern-Connes character for Fredholm modules over a C*-algebra without summability restrictions, taking va…
