Comments on “Structural Invariant Subspaces of Singular Hamiltonian Systems and Nonrecursive Solutions of Finite-Horizon Optimal Control Problems”

In this note it is shown that the main result of [1], concerning a characterization of a pair of structural invariant subspaces associated with the extended symplectic system, is a particular case of a result presented in [2] and [3] within a more general and rigorous context. We also analyse the pr...
