Geometric construction of classes in van Daele's K-theory
Collin Mark Joseph, Ralf Meyer
We describe explicit generators for the "real" K-theory of "real" spheres in van Daele's picture. Pulling these generators back along suitable maps from tori to spheres produces a…
Local cyclic homology for nonarchimedean Banach algebras
Devarshi Mukherjee, Ralf Meyer
Let V be a complete discrete valuation ring with uniformiser p. We introduce an invariant of Banach V-algebras called local cyclic homology. This invariant is related to analytic c…
Analytic cyclic homology in positive characteristic
Ralf Meyer, Devarshi Mukherjee
Let be a complete discrete valuation ring with residue field . We define a cyclic homology theory for algebras over , by lifting them to free algebras o…
The spectrum of equivariant Kasparov theory for cyclic groups of prime order
Ivo Dell'Ambrogio, Ralf Meyer
We compute the Balmer spectrum of the equivariant bootstrap category of separable -C*-algebras when is a group of prime order.
Non-Archimedean analytic cyclic homology
Guillermo Cortiñas, Ralf Meyer, Devarshi Mukherjee
Let be a complete discrete valuation ring with fraction field of characteristic zero and with residue field . We introduce analytic cyclic homology of complete…
On the classification of group actions on C*-algebras up to equivariant KK-equivalence
Ralf Meyer
We study the classification of group actions on C*-algebras up to equivariant KK-equivalence. We show that any group action is equivariantly KK-equivalent to an action on a simple,…
