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…
Braided free orthogonal quantum groups
Ralf Meyer, Sutanu Roy
We construct some braided quantum groups over the circle group. These are analogous to the free orthogonal quantum groups and generalise the braided quantum SU(2) groups for comple…
Noncommutative Cartan C*-subalgebras
B. K. Kwasniewski, R. Meyer
We characterise Exel's noncommutative Cartan subalgebras in several ways using uniqueness of conditional expectations, relative commutants, or purely outer inverse semigroup action…
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,…
