  - 'Optimal control problems with symmetries often admit a non stationary turnpike
    property called trim turnpike, which characterizes the convergence of optimal
    solutions to certain symmetry induced trajectories called trim primitives. In
    this paper we establish an exponential trim turnpike property for a class of optimal
    control problems with structural properties related to Abelian Lie group symmetries.
    The key ingredient of our approach is the introduction of an appropriate reduced
    optimal control problem. We show that extremals of the original problem can be
    characterized through a reduced Hamiltonian boundary value problem that coincides
    with the optimality system of the reduced problem. Under a hyperbolicity assumption
    on the equilibrium of the corresponding reduced Hamiltonian system we prove that
    optimal trajectories remain exponentially close, up to boundary layers near the
    endpoints, to a trim primitive defined by the static reduced problem. The theoretical
    results are illustrated on three representative examples: linear and nonlinear
    problems with quadratic cost and the Kepler orbital transfer problem.@eng'
