| Abstract: | The paper extends to complex Hamiltonian systems previous workof the authors on the Sims extension of the Titchmarsh–Weyltheory for Sturm–Liouville equations with complex potentials,and analyses the spectral properties of associated non-self-adjointoperators. 2000 Mathematics Subject Classification 34B20, 34Lxx. |
