Meet the concept

↗

For an nn-dimensional system, the lecture states there are nn Lyapunov exponents λi\lambda_i, matching the number of state-space dimensions.

Conditions: Stated for an nn-dimensional dynamical system.; The clip does not discuss degeneracies or zero exponents separately.

Understand why

↗

For general trajectories not confined exactly to a single stable or unstable manifold, the lecture argues that the largest positive Lyapunov exponent controls the long-time behavior. This is summarized on the slide as λ1\lambda_1 dominating as t→∞t\to\infty.

Conditions: Trajectory experiences a mix of stable and unstable effects.; Looking at the long-time limit.
