A Reduce program
for Lie group analysis of differential equations
ReLie is a Reduce program that may be useful for investigating Lie group properties of differential equations.
Reduce is a general purpose computer algebra system whose development started by Anthony Hearn. It is written in a Lisp dialect (Portable Standard Lisp); since December 2008 it is an open source program (available for all platforms).
Reduce is designed as an interactive system, but naturally it can also operate in a batch processing.
The program ReLie is extensively described in the paper
F. Oliveri, "ReLie: a Reduce program for Lie group analysis of differential equations", Symmetry, 13, 1826 (1-39), 2021. Download PDF.
