Abstract
This is the second part of a series of papers which bridges the Chang–Weinberger–Yu relative higher index and geometry of almost flat Hermitian vector bundles on manifolds with boundary. In this paper, we apply the description of the relative higher index given in part I to establish the relative version of the Hanke–Schick theorem, which relates the relative higher index with the index pairing of K-homology cycles and almost flat relative vector bundles. We also deal with the quantitative version and the dual problem of this theorem.
