It has to be said that it happens often that proofs of a theorem, that are very different in spirit, rely on very similar computations in the core. | |

It seems to me that the proof is always along the lines of rewriting the ODE as an integral equation, using a discrete approximation of the definite integral, and iterating. Isn't using Euler or Runge-Kutta just using a better discrete approximation for the integral. | |
