RT Book, Section T1 Hamiltonian Formulation and Order Reduction for Nonlinear Splines in the Euclidean 3-Space A1 Muñoz Masqué, Jaime A1 Pozo Coronado, Luis Miguel AB The authors use the procedure developed in [9] to develop a Hamiltonian structure into the variational problem given by the integral of the squared curvature on the spatial curves.The solutions of that problem are the elasticae or nonlinear splines. The symmetry of the problem under rigid motions is then used to reduce the Euler–Lagrange equations to a firstorder dynamical system. PB Natsional. Akad. Nauk Ukraïni, Inst.
