Spectral Asymmetry and Index Theory on Manifolds with Generalised Hyperbolic Cusps
Spectral Asymmetry and Index Theory on Manifolds with Generalised Hyperbolic Cusps
We consider a complete Riemannian manifold, which consists of a compact interior and one or more φ-cusps: infinitely long ends of a type that includes cylindrical ends and hyperbolic cusps.Here φ is a function of the radial coordinate that describes the shape of such an end.Given an action by a …
