The index of transversally elliptic complexes
We study a geometric generalization of the time-dependent Schrödinger equation for the harmonic oscillatorwhere is the Laplace-Beltrami operator with respect to a “scattering metric” on a compact manifold with boundary (the class of scattering metrics is a generalization of asymptotically Euclidean metrics on , radially compactified to the ball) and is a perturbation of , with a boundary defining function for (e.g. in the compactified Euclidean case). Using the quadratic-scattering...
