“…The criteria for the existence of trajectories of the energy that grows up to infinity are known for sufficiently large initial energies [10,24,29,30,44,45,80,81]. The results of the present paper can be used to establish the generic existence of orbits of unbounded energy for all possible values of initial energy.…”

“…Arnold's paper inspired a large number of studies in the longtime stability of actions, the problem which is known as "Arnold diffusion". It has been attracting significant attention recently and we refer the reader to papers [11,31,33,[40][41][42][43]54,57,[60][61][62][68][69][70]76,82,84] for a more detailed discussion.…”

“…A system of this type is called a priori unstable. The drift of orbits along the cylinder has been actively studied in the last decade [3][4][5][7][8][9]12,[18][19][20]22,27,28,[31][32][33][34]70,87,88], including the problem of genericity of this phenomenon and instability times. It should be noted that the Arnold diffusion can be much faster in this case.…”
Abstract:We assume that a symplectic real-analytic map has an invariant normally hyperbolic cylinder and an associated transverse homoclinic cylinder. We prove that generically in the real-analytic category the boundaries of the invariant cylinder are connected by trajectories of the map.

“…This excludes possibly interesting applications. Settings where a noncompact, general geometric version of normal hyperbolicity may be useful include chemical reaction dynamics [Uze+02] and problems in classical and celestial mechanics [DLS06].…”

“…It seems to be a well-known belief by many experts that the theory of normal hyperbolicity can be extended to a general noncompact setting [DLS06,p. 165].…”
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
