Abstract:
We give Bohr–Sommerfeld rules corresponding to quasi-eigenvalues in the pseudospectrum for a one-dimensional $h$-pseudodifferential operator verifying PT symmetry.
Keywords:
Bohr–Sommerfeld rule, $h$-pseudodifferential operator, PT symmetry, principal symbol, sub-principal symbol, Weyl quantization, quasi-mode.
