Juriev D.V. Topics in nonhamiltonian interaction of hamiltonian dynamic systems (23K, TeX) ABSTRACT. An algebraic description of nonhamiltonian interaction of hamiltonian dynamic systems is presented. Some "topical" examples (noncanonically coupled rotators and Euler-Arnold tops, noncanonically copuled oscillators and their chains, "elastoplastic" spring, etc.) are considered. The subject is treated purely mathematically without any specifications of concrete physical implications of a possible interest.
