WitrynaProof by Picard iteration of the Existence Theorem. There is a technique for proving that a solution exists, which goes back to Émile Picard (1856—1941). Here is a simplified version of his proof. The (important) details follow below. Not knowing any solution to the ODE, we begin with a first guess, namely x0(t) = x0. Witryna1 lip 2006 · Abstract.
