摘要：
The condition for Lie point symmetries for reduced Ermakov systems is solved yielding three families of systems. SL(2, R) is always a group of symmetries when frequencies depends on time only. However, the generator of symmetries in more general cases have a contribution not associated with the SL(2, R) group. (C) 2004 Elsevier B.V. All rights reserved.
