Dynamical Stability in Lagrangian Systems

  title={Dynamical Stability in Lagrangian Systems},
  author={Philip Boyland and Christopher Gol'e},
  journal={arXiv: Dynamical Systems},
The first part of this paper surveys results on time-periodic Lagrangian systems on a hyperbolic manifolds. Results of the authors show that the dynamics of such systems are, in a precise sense, at least as complicated as those of the geodesic flow of the hyperbolic metric. The second part of the paper presents original results on autonomous Lagrangian systems on the two torus including a precise description of Mather’s beta function. Examples are given of mechanical systems with non-strictly…

A diverse range of more sophisticated examples of dynamical system for which quite simple topological hypotheses imply very complicated behaviour are produced and their relevance to physical applications is explored.


Lagrangian systems on hyperbolic manifolds
This paper gives two results that show that the dynamics of a time-periodic Lagrangian system on a hyperbolic manifold are at least as complicated as the geodesic flow of a hyperbolic metric. Given a
Periodic orbits for Hamiltonian systems in cotangent bundles
We prove the existence of at least cl(M) periodic orbits for certain time-dependent Hamiltonian systems on the cotangent bundle of an arbitrary compact manifold M. These Hamiltonians are not
Mather Sets for Twist Maps and Geodesics on Tori
The title refers to a theory which is based on independent research in three different fields—differential geometry, dynamical systems and solid state physics—and which has attracted growing interest
Generic properties and problems of minimizing measures of Lagrangian systems
It is proved here that minimizing measures of a Lagrangian flow are invariant and the Lagrangian is cohomologous to a constant on the support of their ergodic components. Moreover, it is shown that
Mather sets for plane Hamiltonian systems
Recently Mather (Ma) developed a theory for area preserving monotone twist maps of an annulus, the main result of which is the generalization of the notion of an invariant curve of such maps. An easy
Symplectic maps, variational principles, and transport
Symplectic maps are the discrete-time analog of Hamiltonian motion. They arise in many applications including accelerator, chemical, condensed-matter, plasma, and fluid physics. Twist maps correspond
Action minimizing invariant measures for positive definite Lagrangian systems
In recent years, several authors have studied "minimal" orbits of Hamiltonian systems in two degrees of freedom and of area preserving monotone twist diffeomorphisms. Here, "minimal" means action
Consequences of contractible geodesics on surfaces
The geodesic flow of any Riemannian metric on a geodesically convex surface of negative Euler characteristic is shown to be semi-equivalent to that of any hyperbolic metric on a homeomorphic surface
Topological methods in surface dynamics
Abstract This paper surveys applications of low-dimensional topology to the study of the dynamics of iterated homeomorphisms on surfaces. A unifying theme in the paper is the analysis and application
