Eigenvalues of Autocovariance Matrix: A Practical Method to Identify the Koopman Eigenfrequencies

Yicun Zhen, Bertrand Chapron, Etienne Memin +1

To infer eigenvalues of the infinite-dimensional Koopman operator, we study the leading eigenvalues of the autocovariance matrix associated with a given observable of a dynamical s…
