A more general method to classify up to equivariant KK-equivalence II: Computing obstruction classes
Ralf Meyer
We describe Universal Coefficient Theorems for the equivariant Kasparov theory for C*-algebras with an action of the group of integers or over a unique path space, using KK-valued…
Dagger completions and bornological torsion-freeness
Ralf Meyer, Devarshi Mukherjee
We define a dagger algebra as a bornological algebra over a discrete valuation ring with three properties that are typical of Monsky-Washnitzer algebras, namely, completeness, born…
Stone duality and quasi-orbit spaces for generalised C*-inclusions
B. K. Kwaśniewski, R. Meyer
Let and be -algebras with . Exploiting the duality between sober spaces and spatial locales, and the adjunction between restriction and induction for…
Coarse geometry and topological phases
Eske Ellen Ewert, Ralf Meyer
We propose the Roe C*-algebra from coarse geometry as a model for topological phases of disordered materials. We explain the robustness of this C*-algebra and formulate the bulk-ed…
C*-Algebras for partial product systems over N
Devarshi Mukherjee, Ralf Meyer
We define partial product systems over N. They generalise product systems over N and Fell bundles over Z. We define Toeplitz C*-algebras and relative Cuntz-Pimsner algebras for the…
