Normally hyperbolic
Web15 de fev. de 2024 · The invariant manifold obtained in Theorem 1 is nonuniformly normally hyperbolic if δ > 0 is small enough. Remark 1. Note that Eq. (1.1) has a trivial invariant manifold W: = {(0, y): 0 ∈ X, y ∈ Y}. Assumptions (A1) and (A2) together with the inequality α > (2 + σ) μ given in (A4) imply that W is nonuniformly normally hyperbolic with ... WebApparently the limit of a normally-hyperbolic slow manifold comprises a family of hyperbolic fixed points parameterized by x ∈ X for the fast-slow system’s limiting short timescale dynamics. Therefore dynamics in the vicinity of a normally-hyperbolic slow manifold tend to be rapidly attractive in some directions and rapidly repulsive in others.

The difference can be described heuristically as follows: For a manifold to be normally hyperbolic we are allowed to assume that the dynamics of itself is neutral compared with the dynamics nearby, which is not allowed for a hyperbolic set.
