Geometric, topological and dynamical properties of conformally symplectic systems, normally hyperbolic invariant manifolds, and scattering maps

Marian Gidea, Rafael de la Llave, Tere M-Seara

Conformally symplectic diffeomorphisms $f : M \to M$ transform a symplectic form $ω$ on a manifold M into a multiple of itself, $f^{*} ω = η ω$ . We assume $ω$ is bounded, as some…

Persistence of hyperbolic solutions of ODE's under functional perturbations: Applications to the motion of relativistic charged particles

Joan Gimeno, Rafael de la Llave, Jiaqi Yang

We rigorously construct a variety of orbits for certain delay differential equations, including the electrodynamic equations formulated by Wheeler and Feynman in 1949. These equati…
