The Branch Cut and Quasi-normal Modes at Large Imaginary Frequency in Schwarzschild Space-time

Marc Casals, Adrian C. Ottewill

The 'retarded' Green function for fields propagating on a Schwarzschild black hole spacetime possesses a branch cut on the complex frequency plane. Classically, the branch cut is i…
