Expanders are counterexamples to the $ℓ^{p}$ coarse Baum-Connes conjecture

Yeong Chyuan Chung, Piotr W. Nowak

We consider an $ℓ^{p}$ coarse Baum-Connes assembly map for $1 < p < \infty$ , and show that it is not surjective for expanders arising from residually finite hyperbolic groups.

Dynamical Complexity and $K$ -Theory of $L^{p}$ Operator Crossed Products

Yeong Chyuan Chung

We apply quantitative (or controlled) $K$ -theory to prove that a certain $L^{p}$ assembly map is an isomorphism for $p \in [1, \infty)$ when an action of a countable discrete group $Γ$ …

Quantitative $K$ -theory for Banach algebras

Yeong Chyuan Chung

Quantitative (or controlled) $K$ -theory for $C^{*}$ -algebras was used by Guoliang Yu in his work on the Novikov conjecture, and later developed more formally by Yu together with Herv…
