The application of computer algebra for determining Lie and Lie–Bäcklund (LB) symmetries of differential equations is considered. Algorithms for calculating the symmetries are developed and implemented on the basis of computer algebra systems REDUCE, AMP and FORMAC. The most effective and advanced program is written in FORMAC. It finds LB symmetries(More)
We propose in this work aprogram for determining Lie-Backlund (LB) symmetries of (partial or ordinary) differential equations and for classification of equations containing arbitrary functions and parameters with respect to symmetries of this kind. The program was implemented in Turbo C language and designed in such a way to be more effective for systems of(More)
