Abstract
Families of unbounded commuting self-adjoint operators have been studied, connected by non-Lie relations with a unitary one. The possibility of a structural description of such a family of operators is based on the properties of ergodic measures of the corresponding many-dimensional dynamical system (d.s.). A number of conditions imposed on d.s., making the operator problem “tame,” has been presented.
