Normally Hyperbolic Invariant Manifolds in Dynamical Systems

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. A normally hyperbolic invariant manifold (NHIM) is a natural generalization of a hyperbolic fixed point and a hyperbolic set. 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. NHIMs were introduced by Neil Fenichel in 1972. In this and subsequent papers, Fenichel proves that NHIMs possess stab… fluff tube https://megaprice.net

WebDefinition. In general terms, a smooth dynamical system is called hyperbolic if the tangent space over the asymptotic part of the phase space splits intotwo complementary directions, one which is contracted and the other which is expanded under the action of the system. In the classical, so‐calleduniformly hyperbolic case, the asymptotic part ...
