Title: The fibred coarse embedding and the coarse Novikov conjecture

Abstract: The coarse Novikov conjecture claims that a certain assembly map from the K-homology of a metric space to the K-theory of its Roe algebra is injective. It was verified for a large class of metric spaces including the space admitting a fibred coarse embedding into Hilbert space. In this talk, I will talk about the notion of fibred coarse embedding introduced by X. Chen, Q. Wang and G. Yu, and its generalization, so called FCE-by-FCE structure. I will also talk about the coarse Novikov conjecture for a space with an FCE-by-FCE structure. This is based a joint work with L. Guo, Q. Wang and G. Yu.
