  text: Many PDEs (Burgers' equation, KdV, Camassa-Holm, Euler's fluid equations,
    …) can be formulated as infinite-dimensional Lie-Poisson systems. These are Hamiltonian
    systems on manifolds equipped with Poisson brackets. The Poisson structure is
    connected to conservation properties and other geometric features of solutions
    to the PDE and, therefore, of great interest for numerical integration. For the
    example of Burgers' equations and related PDEs we use Clebsch variables to lift
    the original system to a collective Hamiltonian system on a symplectic manifold
    whose structure is related to the original Lie-Poisson structure. On the collective
    Hamiltonian system a symplectic integrator can be applied. Our numerical examples
    show excellent conservation properties and indicate that the disadvantage of an
    increased phase-space dimension can be outweighed by the advantage of symplectic
    integration.

  text: 'A bifurcation is a qualitative change in a family of solutions to an equation
    produced by varying parameters. In contrast to the local bifurcations of dynamical
    systems that are often related to a change in the number or stability of equilibria,
    bifurcations of boundary value problems are global in nature and may not be related
    to any obvious change in dynamical behaviour. Catastrophe theory is a well-developed
    framework which studies the bifurcations of critical points of functions. In this
    paper we study the bifurcations of solutions of boundary-value problems for symplectic
    maps, using the language of (finite-dimensional) singularity theory. We associate
    certain such problems with a geometric picture involving the intersection of Lagrangian
    submanifolds, and hence with the critical points of a suitable generating function.
    Within this framework, we then study the effect of three special cases: (i) some
    common boundary conditions, such as Dirichlet boundary conditions for second-order
    systems, restrict the possible types of bifurcations (for example, in generic
    planar systems only the A-series beginning with folds and cusps can occur); (ii)
    integrable systems, such as planar Hamiltonian systems, can exhibit a novel periodic
    pitchfork bifurcation; and (iii) systems with Hamiltonian symmetries or reversing
    symmetries can exhibit restricted bifurcations associated with the symmetry. This
    approach offers an alternative to the analysis of critical points in function
    spaces, typically used in the study of bifurcation of variational problems, and
    opens the way to the detection of more exotic bifurcations than the simple folds
    and cusps that are often found in examples. '

  text: Symplectic integrators can be excellent for Hamiltonian initial value problems.
    Reasons for this include their preservation of invariant sets like tori, good
    energy behaviour, nonexistence of attractors, and good behaviour of statistical
    properties. These all refer to {\em long-time} behaviour. They are directly connected
    to the dynamical behaviour of symplectic maps φ:M→M' on the phase space under
    iteration. Boundary value problems, in contrast, are posed for fixed (and often
    quite short) times. Symplecticity manifests as a symplectic map φ:M→M' which is
    not iterated. Is there any point, therefore, for a symplectic integrator to be
    used on a Hamiltonian boundary value problem? In this paper we announce results
    that symplectic integrators preserve bifurcations of Hamiltonian boundary value
    problems and that nonsymplectic integrators do not.

  description: |-
    Two smooth map germs are right-equivalent if and only if they
    generate two Lagrangian submanifolds in a cotangent bundle which have the
    same contact with the zero-section. In this paper we provide a reverse direction
    to this classical result of Golubitsky and Guillemin. Two Lagrangian submanifolds of a symplectic manifold have the same contact with a third Lagrangian
    submanifold if and only if the intersection problems correspond to stably right
    equivalent map germs. We, therefore, obtain a correspondence between local
    Lagrangian intersection problems and catastrophe theory while the classical
    version only captures tangential intersections. The correspondence is defined
    independently of any Lagrangian fibration of the ambient symplectic manifold, in contrast to other classical results. Moreover, we provide an extension
    of the correspondence to families of local Lagrangian intersection problems.
    This gives rise to a framework which allows a natural transportation of the
    notions of catastrophe theory such as stability, unfolding and (uni-)versality
    to the geometric setting such that we obtain a classification of families of lo-
    cal Lagrangian intersection problems. An application is the classification of
    Lagrangian boundary value problems for symplectic maps.

  text: 'In this paper we continue our study of bifurcations of solutions of boundary-value
    problems for symplectic maps arising as Hamiltonian diffeomorphisms. These have
    been shown to be connected to catastrophe theory via generating functions and
    ordinary and reversal phase space symmetries have been considered. Here we present
    a convenient, coordinate free framework to analyse separated Lagrangian boundary
    value problems which include classical Dirichlet, Neumann and Robin boundary value
    problems. The framework is then used to prove the existence of obstructions arising
    from conformal symplectic symmetries on the bifurcation behaviour of solutions
    to Hamiltonian boundary value problems. Under non-degeneracy conditions, a group
    action by conformal symplectic symmetries has the effect that the flow map cannot
    degenerate in a direction which is tangential to the action. This imposes restrictions
    on which singularities can occur in boundary value problems. Our results generalise
    classical results about conjugate loci on Riemannian manifolds to a large class
    of Hamiltonian boundary value problems with, for example, scaling symmetries. '
