A mod 2 index theorem for pin$^-$ manifolds

Abstract

We establish a mod 2 index theorem for real vector bundles over 8k+2 dimensional compact pin^- manifolds. The analytic index is the reduced η\eta invariant of (twisted) Dirac operators and the topological index is defined through KOKO-theory. Our main result extends the mod 2 index theorem of Atiyan and Singer to non-orientable manifolds.
