Essential self-adjointness of the wave operator and the limiting absorption principle on Lorentzian scattering spaces
Essential self-adjointness of the wave operator and the limiting absorption principle on Lorentzian scattering spaces
We discuss the essential self-adjointness of wave operators, as well as the limiting absorption principle, in generalizations of asymptotically Minkowski settings. This is obtained via using a Fredholm framework for inverting the spectral family first, and then refining its conclusions to show dense range of \Box-\lambda , \lambda\notin\mathbb R , …
