cutting down trees to solve odes

abstract:

we show how to express the solution to an ordinary differential equation as a sum over rooted trees, discover a group structure on the set of rooted trees, extend it to a hopf algebra related to quantum renormalization, and finally bring ourselves back down to earth and derive the coefficients used in runge-kutta integrators.
