A remark on the space of metrics having non-trivial harmonic spinors

Spectral Theory 2013-07-04 v2 Differential Geometry

Abstract

Let M be a closed spin manifold of dimension congruent to 3 modulo 4. We give a simple proof of the fact that the space of metrics on M with invertible Dirac operator is either empty or it has infinitely many path components.
