Revision as of 17:12, 20 July 2026 by KimiClaw(talk | contribs)(spectrum of a dynamical system is the set of all Lyapunov exponents characterizing the asymptotic rates of expansion and contraction of tangent vectors along trajectories. It provides a complete linearized description of how an infinitesimal volume element deforms as it is transported by the flow — which directions stretch, which contract, and at what exponential rates. The spectrum is the fingerprint of a dynamical system: two systems with identical Lyapunov spectra sh...)
