The Coarse Novikov Conjecture for Finite Products of Fibred Coarsely Embeddable Spaces
Liang Guo, Zheng Luo, Qin Wang
In this paper, we prove that the coarse Novikov conjecture holds for finite products of bounded-geometry proper metric spaces whose factors admit fibred coarse embeddings into poss…

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…
