K-cycles for twisted K-homology

P Baum, A Carey, BL Wang - Journal of K-Theory, 2013 - cambridge.org
We summarise the construction of geometric cycles and their use in describing the Kasparov

Relative geometric assembly and map** cones, part I: the geometric model and applications

RJ Deeley, M Goffeng - Journal of Topology, 2018 - Wiley Online Library
Inspired by an analytic construction of Chang, Weinberger and Yu, we define an assembly
map in relative geometric K‐homology. The properties of the geometric assembly map are …
