On time-dependent Hamiltonian realizations of planar and nonplanar systems

Abstract

In this paper, we elucidate the key role played by the cosymplectic geometry in the theory of time dependent Hamiltonian systems in 2D. We generalize the cosymplectic structures to time-dependent Nambu-Poisson Hamiltonian systems and corresponding Jacobi's last multiplier for 3D systems. We illustrate our constructions with various examples. (C) 2018 Elsevier B.V. All rights reserved.
