Abstract

We demonstrate by explicit computation that an SU(2) gauge instanton does alter the spectrum of a fermion in an external gravitational field. This is contrary to results reported in the literature. Nevertheless when all topological boundary invariants are included the index of the Dirac operator is not changed by the field.
