Abstract
In this paper,the authors study the persistence approximation property for quantitative K-theory of filtered Lp operator algebras.Moreover,they define quantita-tive assembly maps for Lp operator algebras when p ∈[1,∞).Finally,in the case of Lp crossed products and Lp Roe algebras,sufficient conditions for the persistence approxima-tion property are found.This allows to give some applications involving the Lp(coarse)Baum-Connes conjecture.
