Learning Koopman operators for coupled systems via information on governing equations of subsystems

Excerpt

arXiv:2605.01835v2 Announce Type: replace Abstract: Nonlinear coupled systems are ubiquitous in science and engineering. The analysis and modeling of such systems are challenging due to their high dimensionality and complex interactions among subsystems. In recent years, operator-theoretic methods based on the Koopman operator have attracted attention as a powerful tool for analyzing and modeling nonlinear dynamical systems. Extended dynamic mode decomposition (EDMD) is one of the most popular m
