Description

In this lecture, we discuss some strategy to compute the K-theory of operator algebras equipped with a propagation structure.
Prominent examples of such algebras are provided by Roe algebras, group C-algebras and cross-products C-algebras.
The main tools we use to achieve this goal is quantitative K-theory and in this framework, coarse Mayer-Vietoris controlled exact sequences.
