Exact invariants for time-dependent nonlinear Hamiltonian systems

Conference ·
Two methods, one based on canonical transformations and one based on an assumed structure, are used to determine exact invariants for certain Hamiltonians of the type H = 1/2 p/sup 2/ + V(q,t). Invariants are found explicitly for a class of nonlinear, time-dependent potentials V(q,t). The former method is then developed to find exact invariants for Hamiltonians of the form H = H(q,p,rho(t),rho(t)).
