This talk will be about the systematic simplification of differential equations.
After giving a geometric reformulation of the concept of a differential equation using prolongations, I will show how we can prolong group actions relatively easily at the level of Lie algebras. I will then discuss group-invariant solutions.
The key example will be the heat equation.
