Data-driven spectral analysis of the Koopman operator
Milan Korda, Mihai Putinar, Igor Mezić
Starting from measured data, we develop a method to compute the fine structure of the spectrum of the Koopman operator with rigorous convergence guarantees. The method is based on…

Koopman Spectrum for Cascaded Systems
Ryan Mohr, Igor Mezić
This paper considers the evolution of Koopman principal eigenfunctions of cascaded dynamical systems. If each component subsystem is asymptotically stable, the matrix norms of the…

Study of dynamics in post-transient flows using Koopman mode decomposition
Hassan Arbabi, Igor Mezić
The Koopman Mode Decomposition (KMD) is a data-analysis technique which is often used to extract the spatio-temporal patterns of complex flows. In this paper, we use KMD to study t…
