Well-Balanced and Asymptotic Preserving IMEX-Peer Methods
Well-Balanced and Asymptotic Preserving IMEX-Peer Methods
Peer methods are a comprehensive class of time integrators offering numerous degrees of freedom in their coefficient matrices that can be used to ensure advantageous properties, e.g. A-stability or super-convergence. In this paper, we show that implicit-explicit (IMEX) Peer methods are well-balanced and asymptotic preserving by construction without additional constraints …
