S. Bouquet et Hr. Lewis, EXTENSION OF GIACOMINI RESULTS CONCERNING INVARIANTS FOR ONE-DIMENSIONAL TIME-DEPENDENT POTENTIALS, Journal of mathematical physics, 37(11), 1996, pp. 5496-5508
One-dimensional time-dependent potentials are considered for which an
invariant can be expressed in terms of the potential and the momentum
according to the formulation of Giacomini. New solutions of Giacomini'
s equations are derived. In addition, possibilities are discussed for
extending Giacomini's approach to more general systems. (C) 1996 Ameri
