# ReLie

## A Reduce program

for Lie group analysis of differential equations

Francesco Oliveri

**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 described in the paper

F. Oliveri, "ReLie: a Reduce program for Lie group analysis
of differential equations",
submitted to Foundations of Computational Mathematics, 2021.
