On invariant measures for classical dynamical systems with infinite-dimensional phase space

A. A. Arsen'ev


Abstract: The Kubo–Martin–Schwinger state is constructed for a Hamiltonian dynamical system whose phase space is Hilbert space, with Hamiltonian representable as the sum of two terms: the square of the norm and a function that is smooth on the completion of the original space in the nuclear norm.
