Quantitative $K$-theory for Banach algebras

Abstract

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