Twisted coarse Baum–Connes conjecture with coefficients
Twisted coarse Baum–Connes conjecture with coefficients
Let be a metric space with bounded geometry, let be its Rips complex at scale , and let be a coarse -algebra. The twisted assembly map is
Here is the twisted localization algebra and is the twisted Roe algebra with coefficients in . Twisted coarse Baum–Connes conjecture with coefficients. For every coarse -algebra , the map is an isomorphism. The paper proves this conjecture for spaces with suitable coarse-fibration structures, including cases whose base and fiber satisfy the corresponding conjecture; its general status is not resolved here.
