Exotic crossed products and the Baum-Connes conjecture
Alcides Buss, Siegfried Echterhoff, Rufus Willett
We study general properties of exotic crossed-product functors and characterise those which extend to functors on equivariant C*-algebra categories based on correspondences. We sho…

A metric approach to limit operators
Jan Spakula, Rufus Willett
We extend the limit operator machinery of Rabinovich, Roch, and Silbermann from to (bounded geometry, strongly) discrete metric spaces. We do not assume the presence…

Random graphs, weak coarse embeddings, and higher index theory
Rufus Willett
This paper studies higher index theory for a random sequence of bounded degree, finite graphs with diameter tending to infinity. We show that in a natural model for such random seq…
