| contents | We study Hamiltonian flows in a real separable Hilbert space endowed with a symplectic structure. Measures on the Hilbert space that are invariant with respect to the flows of completely integrable Hamiltonian systems are investigated. These construction gives the opportunity to describe Hamiltonian flows in the phase space by means of unitary groups in the space of functions that are quadratically integrable by the invariant measure. Invariant measures are applied to the study of model linear Hamiltonian systems that admit features of the type of unlimited increase in kinetic energy over a finite time. Due to this approach solutions of Hamilton equations that admit singularities can be described by means of the phase flow in the extended phase space and by the corresponding Koopman representation of the unitary |
