Dynamics of resonances for 0th order pseudodifferential operators
Jian Wang
We study the dynamics of resonances of analytic perturbations of 0th order pseudodifferential operators . In particular, we prove a Fermi golden rule for resonances of …

The scattering matrix for 0th order pseudodifferential operators
Jian Wang
We use microlocal radial estimates to prove the full limiting absorption principle for , a self-adjoint 0th order pseudodifferential operator satisfying hyperbolic dynamical ass…
