摘要：Persistence approximation property was introduced by Herv’e Oyono-Oyono and

Guoliang Yu. This property provides a geometric obstruction to Baum-Connes conjecture.

In this paper, we mainly discuss the persistence approximation property for maximal Roe

algebras. We show that persistence approximation property of maximal Roe algebras

follows from maximal coarse Baum-Connes conjecture. In particular, let X be a discrete

metric space with bounded geometry, assume X admits a fibred coarse embedding into

Hilbert space and X is coarsely uniformly contractible, then the maximal Roe algebra of this space has persistence approximation property. We also give an application of the quantitative K-theory to the maximal coarse Baum-Connes conjecture.
