Several equivalent characterizations are derived which extend the characterizations of [38] to the general non-minimal case. An explicit construction of the transformation matrices is presented. The methods are applied in the stability analysis of disc brake squeal.en512 Algebraport-Hamiltonian systempassivitystabilitysystem transformationlinear matrix inequalityLyapunov inequalityeven pencilquadratic eigenvalue problemPreprint
