Abstract
We introduce the notion of the joint spectral flow, which is a generalization of the spectral flow, by using Segal’s model of the connective -theory spectrum. We apply it for some localization results of indices motivated by Witten’s deformation of Dirac operators, and rephrase some analytic techniques in terms of topology.
