Appendix A

This appendix contains the MAPLE v4 programs used to generate the various tables in the paper "Spectral enclosures and complex resonances for general self-adjoint operators".

• Eigenvalues in gaps, used for tables 1 and 2.
• Exact resonance calculations, used for table 3.
• The complex resonances used to generate figures 3 and 4 in the paper.
• The almost mathieu equation.
