Semiclassical estimates near threshold energies and resonance counting on Schwarzschild black holes
Thomas Stucker
The paper establishes a Weyl law for the count of quasinormal modes of a Schwarzschild black hole by developing a new semiclassical pseudodifferential calculus near threshold energ…

Quasinormal modes for the Kerr black hole
Thomas Stucker
We provide a rigorous definition of quasinormal modes for the Kerr black hole. They are obtained as the discrete set of poles of the meromorphically continued cutoff resolvent. The…
