Koopman-Based Learning of Infinitesimal Generators without Operator Logarithm

open access: yes
The Koopman operator has gained significant attention in recent years for its ability to verify evolutionary properties of continuous-time nonlinear systems by lifting state variables into an infinite-dimensional linear vector space.

Finite-data Error Bounds for Approximating the Koopman Operator

open access: yes
The Koopman operator is a powerful tool for the study of dynamical systems that allows the study of nonlinear systems through the lens of observables functions forming an equivalent linear formulation of the dynamics in an infinite-dimensional space ...
