K-theory of the maximal and reduced Roe algebras of metric spaces with A-by-CE coarse fibrations

Liang Guo, Zheng Luo, Qin Wang +1

Let $X$ be a discrete metric space with bounded geometry. We show that if $X$ admits an "A-by-CE coarse fibration", then the canonical quotient map $λ : C_{m a x}^{*} (X) \to C^{*} (X)$ fro…

The equivariant coarse Baum-Connes conjecture for metric spaces with proper group actions

Jintao Deng, Benyin Fu, Qin Wang

The equivariant coarse Baum-Connes conjecture interpolates between the Baum-Connes conjecture for a discrete group and the coarse Baum-Connes conjecture for a proper metric space.…

The coarse Novikov conjecture for extensions of coarsely embeddable groups

Qin Wang, Yazhou Zhang

Let $(1 \to N_{n} \to G_{n} \to Q_{n} \to 1)_{n \in N}$ be a sequence of extensions of countable discrete groups. Endow $(G_{n})_{n \in N}$ with metrics associated to proper l…

The coarse Baum-Connes conjecture for certain relative expanders

Jintao Deng, Qin Wang, Guoliang Yu

Let $(1 \to N_{m} \to G_{m} \to Q_{m} \to 1)_{m \in N}$ be a sequence of extensions of finite groups such that their coarse disjoint unions have bounded geometry. In thi…
