  • Routh Reduction by Stages 
    Langerock, B.; Mestdag, T.; Vankerschaver, J. (Symmetry, Integrability and Geometry: Methods and Applications, 2011)
    This paper deals with the Lagrangian analogue of symplectic or point reduction by stages. We develop Routh reduction as a reduction technique that preserves the Lagrangian nature of the dynamics. To do so we heavily rely ...
  • Un-Reduction of Systems of Second-Order Ordinary Differential Equations 
    García-Toraño Andrés, E.; Mestdag, T. (Symmetry, Integrability and Geometry: Methods and Applications, 2016)
    In this paper we consider an alternative approach to ''un-reduction''. This is the process where one associates to a Lagrangian system on a manifold a dynamical system on a principal bundle over that manifold, in such a ...
