Abstract: | Quantitative (or controlled) K-theory for -algebras was used by Guoliang Yu in his work on the Novikov conjecture, and later developed more formally by Yu together with Hervé Oyono-Oyono. In this paper, we extend their work by developing a framework of quantitative K-theory for the class of algebras of bounded linear operators on subquotients (i.e., subspaces of quotients) of spaces. We also prove the existence of a controlled Mayer–Vietoris sequence in this framework. |
