Spectral singularities for Non-Hermitian one-dimensional Hamiltonians: puzzles with resolution of identity

A. A. Andrianov, F. Cannata, A. V. Sokolov

We examine the completeness of bi-orthogonal sets of eigenfunctions for non-Hermitian Hamiltonians possessing a spectral singularity. The correct resolutions of identity are constr…
