Data-Driven Spectral Analysis with Pseudo-Resolvent Koopman Operator

Published:Dec 31, 2025 16:33
1 min read
ArXiv

Analysis

This paper introduces a data-driven method to analyze the spectrum of the Koopman operator, a crucial tool in dynamical systems analysis. The method addresses the problem of spectral pollution, a common issue in finite-dimensional approximations of the Koopman operator, by constructing a pseudo-resolvent operator. The paper's significance lies in its ability to provide accurate spectral analysis from time-series data, suppressing spectral pollution and resolving closely spaced spectral components, which is validated through numerical experiments on various dynamical systems.
Reference

“The method effectively suppresses spectral pollution and resolves closely spaced spectral components.”
