Learning Global Linear Representations of Truly Nonlinear Dynamics
T Breunung, F Kogelbauer - arXiv preprint arXiv:2408.03437, 2024 - arxiv.org
While linear systems are well-understood, no explicit solution exists for general nonlinear
systems. Thus, it is desirable to make the understanding of linear system available in the …

On the lifting and reconstruction of nonlinear systems with multiple invariant sets
S Pan, K Duraisamy - Nonlinear Dynamics, 2024 - Springer
The Koopman operator provides a linear perspective on non-linear dynamics by focusing on
the evolution of observables in an invariant subspace. Observables of interest are typically …
