We prove sharp uniform L-bounds for low-lying eigenfunctions of non-self-adjoint semiclassical pseudodifferential operators P on R whose principal symbols are doubly-characteristic at the origin of R. Our bounds hold under two main assumptions on P : (1) the total symbol of P extends holomorphically to a tubular neighborhood of R in C, and (2) the quadratic approximation to the principal symbol of P at the origin is elliptic along its singular space. Most notably, our assumptions on the…

TLDR
For a one dimensional setting, the Dirichlet realization of the operator-h^2\Delta+iV in the semi-classical limit $h\to0$ is considered, and the complete asymptotic expansion, in powers of $h$, of each eigenvalue is obtained.

We consider a class of pseudodifferential operators with a doubly characteristic point, where the quadratic part of the symbol fails to be elliptic but obeys an averaging assumption. Under suitable
