Applied Koopman Theory for Partial Differential Equations and Data-Driven Modeling of Spatio-Temporal Systems
Figure 5
(a)–(d) Koopman spectra of the four kernels considered in (37) and (38a)–(38c), respectively. The red spectra are the Koopman spectra generated from the rank observable which provides an exceptionally accurate reconstruction of the NLS dynamics.
