Statistical inference in non-Hamiltonian dynamics

We assume that the formal results of the maximum-entropy approach for the description of some quantal systems remain valid in the presence of a perturbation that cannot be formulated in terms of a Hamiltonian, if the dynamical laws for a convenient set of observables are known. As an example we stud...
