Ghostly ideals in uniform Roe algebras

Qin Wang, Jiawen Zhang

In this paper, we investigate the ideal structure of uniform Roe algebras for general metric spaces beyond the scope of Yu's property A. Inspired by the ideal of ghost operators co…

Coarse embeddings at infinity and generalized expanders at infinity

Jintao Deng, Liang Guo, Qin Wang +1

We introduce a notion of coarse embedding at infinity into Hilbert space for metric spaces, which is a weakening of the notion of fibred coarse embedding and a far generalization o…

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 be a discrete metric space with bounded geometry. We show that if admits an "A-by-CE coarse fibration", then the canonical quotient map fro…
