Abstract

This paper investigates what is the Hausdorff distance between the set of Euler curves of a Lipschitz continuous differential inclusion and the set of Euler curves for the corresponding convexified differential inclusion. It is known that this distance can be estimated by \(O(\sqrt{h})\), where h is the Euler discretization step. It has been conjectured that, in fact, an estimation O(h) holds. The paper presents results in favor of the conjecture, which cover most of the practically relevant cases. However, the conjecture remains unproven, in general.

In fact, the global boundedness and Lipschitz continuity can be replaced with local ones if all solutions of (1) are contained in a bounded set. Then the formulations of some of the claims in the paper should be somewhat modified. The standing assumptions above are made simpler for more transparency.
