Resolvent Estimates for Normally Hyperbolic Trapped Sets

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… Web19 de nov. de 2024 · The second, independent, result provides microlocal estimates for operators whose null-bicharacteristic flow has a normally hyperbolic invariant … it\\u0027s time for me to come home for christmas

Flows with this … In mathematics, a hyperbolic manifold is a space where every point looks locally like hyperbolic space of some dimension. They are especially studied in dimensions 2 and 3, where they are called hyperbolic surfaces and hyperbolic 3-manifolds, respectively. In these dimensions, they are important because most manifolds can be made into a hyperbolic manifold by a homeomorphism. This i… it\u0027s time for lunch video

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.

We first build 3-dimensional normally hyperbolic invariant cylinders of limited regularity, but of large size, extrapolating on [Be3] and [KZZ]. Once these cylinders are constructed we use versions of Mather variational method developed in Bernard [Be1], Cheng-Yan [CY1, CY2].
