摘要：
Attempts are made to construct exact invariants for a variety of time-dependent classical dynamical systems in three dimensions. We make use of the dynamical algebraic method for this purpose and explore several new systems admitting the invariants. In particular, systems involving both momentum and time dependences in two and three dimensions are investigated within this framework. With reference to the time-dependent case in three dimensions some further generalizations of Ermakov systems are discussed. (C) 1997 Academic Press.
