Bivariant K-theory via correspondences
Heath Emerson, Ralf Meyer
We use correspondences to define a purely topological equivariant bivariant K-theory for spaces with a proper groupoid action. Our notion of correspondence differs slightly from th…
C*-Algebras over Topological Spaces: Filtrated K-Theory
Ralf Meyer, Ryszard Nest
We define the filtrated K-theory of a C*-algebra over a finite topological space X and explain how to construct a spectral sequence that computes the bivariant Kasparov theory over…
Square-integrable coactions of locally compact quantum groups
Alcides Buss, Ralf Meyer
We define and study square-integrable coactions of locally compact quantum groups on Hilbert modules, generalising previous work for group actions. As special cases, we consider sq…
Homological algebra in bivariant K-theory and other triangulated categories. II
Ralf Meyer
We use homological ideals in triangulated categories to get a sufficient criterion for a pair of subcategories in a triangulated category to be complementary. We apply this criteri…
