Two-Scale Exponential Integrators with Uniform Accuracy for Three-Dimensional Charged-Particle Dynamics Under a Strong Magnetic Field

Abstract. The numerical simulation of three-dimensional charged-particle dynamics (CPD) under a strong magnetic field is a basic and challenging algorithmic task in plasma physics. In this paper, we introduce a new methodology to design two-scale exponential integrators for three...

Output Matching Model Reduction for Discrete‐Time Singular Systems With High Index

ABSTRACT In this paper, a new model order reduction approach is presented for reducing large‐scale discrete‐time singular systems with higher index. Based on the regularity of the singular system, the singular system is decomposed into a non‐singular subsystem and a singular subs...
