Symmetry Invariants of Strange Attractors from Jet-Space Embeddings

A method for reconstructing dynamical systems from a scalar time series is proposed, based on replacing delay coordinates with jet-space coordinates—the signal and its time derivatives. A theorem is proved establishing a Lie algebra isomorphism under jet prolongation, which ensures equivariance under the full symmetry...
