The coarse index class with support

Differential Geometry 2025-05-14 v2 K-Theory and Homology

Abstract

We construct the coarse index class with support condition (as an element of coarse KK-homology) of an equivariant Dirac operator on a complete Riemannian manifold endowed with a proper, isometric action of a group. We further show a coarse relative index theorem and discuss the compatibility of the index with the suspension isomorphism.
