概要
This skill provides a specialized workflow for utilizing the CRACK package within REDUCE, specifically designed for finding Lie symmetries and solving complex differential equation systems. It guides users through critical setup steps like functional dependency declarations, manages transitions between batch and interactive solving modes, and provides structured natural language interpretations of mathematical outputs. Whether you are performing similarity reductions or deriving conservation laws, this skill helps navigate case splits, free functions, and symbolic constraints to ensure rigorous mathematical results.
