Description

The purpose of this program is to derive the determining equations for Lie-Baecklund symmetries. The determining equations are derived in a form simplified as far as possible. The program allows an automatic solution of the determining equations for second-order ODEs by using a polynomial ansatz in the dependent variables and derivatives. If the characteristics for second-order ODEs are calculated, the program determines the corresponding integrals of motion.
