The koopman operator

WebThe Koopman operator can trans-form the analysis of a nite-dimensional, nonlinear dynamical system into the analysis of an in nite-dimensional, linear system [25]. Standard spectral analysis of this linear Koopman operator is a powerful methodology to investigate ows arising from nonlinear dynamical systems [31,42,8,32]. In this section, we ... Web1 Oct 2024 · The first one is the Koopman operator construction by mapping the Heisenberg equation of motion on the basis of the coherent states. The second approach is the Schrödinger–Feynman consideration of the Green function in the framework of the path integral. The main issue in the task is the laser field intensity.

WebLiterature Review: Given a dynamical system, its associated Koopman operator (Koopman, 1931, Koopman and Neumann, 1932) is a linear operator characterizing the effect of the dynamics on functions in a (generally infinite-dimensional) linear function space. The values of its eigenfunctions also evolve linearly in time on the trajectories of the system. WebAbstract. We study a class of dynamical systems modelled as stationary Markov chains that admit an invariant distribution via the corresponding transfer or Koopman operator. While data-driven algorithms to reconstruct such operators are well known, their relationship with statistical learning is largely unexplored.
