Abstract: Dynamical systems described by ODEs, DAEs, PDEs or, especially, coupled multiphysical systems are often equipped with multilateral behavior: components, right-hand side or signals show a drastically different activity level, given by very different time scales. Multirate integration scheme aim at exploiting this multirate behavior by integrating the different parts with their respective step sizes, while at the same time preserving the convergence order and stability properties of the underlying schemes.

This mini symposium will present recent advances in developing numerical multirate schemes and highlight the efficient use of these scheme in industrial applications.
