Abstract
A canonical system of differential equations, or Hamiltonian system, is a system of order two of the form Jy′(x) = −zH(x)y(x), x ∈ ℝ+. We characterize the property that the selfadjoint operators associated to a canonical system have resolvents of Hilbert-Schmidt type in terms of the Hamiltonian H as well as in terms of the associated Titchmarsh-Weyl coefficient.
