Lie Point Symmetries for Reduced Ermakov Systems
/ Authors
/ Abstract
Abstract 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.
