Ordinary Differential Equations

Title: Ordinary Differential Equations
Author: Fabian Immler and Johannes Hölzl

Abstract: We formalize initial value problems (IVPs) of ODEs and prove the existence of a unique solution, i.e. the Picard-Lindelöf theorem. We introduce general one-step methods for numerical approximation of the solution and provide an analysis regarding the local and global error of one-step methods. We give an executable specification of the Euler method to approximate the solution of IVPs and prove an explicit bound for the global error. We use arbitrary-precision floating-point numbers and also handle rounding errors when we truncate the numbers for efficiency reasons.
