On the koopman operator of algorithms
WebThe Koopman operator [34] is the linear time evolu- tion operator on an infinite-dimensional function space of observables defined over a dynamical system. The in- 65 vestigation of its spectral properties was pioneered by Igor Mezi´c [41,43] and had been developed mainly in the context of fluid dynamics [42]. WebThis review discusses the theoretical foundations of Koopman operator methods, as well as numerical methods developed over the past two decades to approximate the …
