Find the exact solution to the ivp above as , It is shown that the speed of convergence is quite independent of the step sizes. X!y is a mapping that maps a function in the space of functions xto another function in the space of functions y, The convergence is studied on infinitely long intervals.
Picard S Theorem Youtube from i.ytimg.com It can then be shown, by using the banach fixed point theorem, that the sequence of picard iterates $φ_k$ is convergent and that the limit is a solution to the problem. (as you can write every ode autonomously, i will only look at the autonomous case as the other case is n.
