Abstract:

This paper is devoted to discretization methods for initial value problems for differential inclusions. Main emphasis is laid on set-valued analogues of Runge-Kutta methods.

The following questions are studied:

  1. Does every discrete trajectory approximate some exact solution, and with what accuracy?
  2. Is every exact solution approximated, and with what accuracy, by some discrete trajectory?
  3. What is the error between the discrete reachable set and the exact reachable set with respect to Hausdorff distance?

The material is presented as a survey, containing simultaneously a series of new results with complete proofs.
