Abstract:
It is shown that a nondegenerate linear system that admits a nondegenerate quadratic from as a first integral can be represented in several different ways as a Hamiltonian system of differential equations; we present a “complete” family of the corresponding symplectic structures and Hamiltonians. We discuss possible generalizations of this result including the case of linear systems of differential equations with periodic coefficients.References
