Resonances for non-analytic potentials
André Martinez, Thierry Ramond, Johannes Sjoestrand
We consider semiclassical Schroedinger operators on R^n, with C^\infty potentials decaying polynomially at infinity. The usual theories of resonances do not apply in such a non-ana…
Eigenvalue distributions and Weyl laws for semi-classical non-self-adjoint operators in 2 dimensions
Johannes Sjoestrand
In this note we compare two recent results about the distribution of eigenvalues for semi-classical pseudodifferential operators in two dimensions. For classes of analytic operator…
Some results on non-self-adjoint operators, a survey
Johannes Sjoestrand
This text is a survey of recent results obtained by the author and collaborators on different problems for non-self-adjoint operators. The topics are: Kramers-Fokker-Planck type op…
Tunnel effect for Kramers-Fokker-Planck type operators: return to equilibrium and applications
Frederic Herau, Michael Hitrik, Johannes Sjoestrand
In the first part of this work, we consider second order supersymmetric differential operators in the semiclassical limit, including the Kramers-Fokker-Planck operator, such that t…
