Some recent results on higher-order Lagrangean systems are presented. The concept of higher-order Lagrangean system as a Lepagean two-form defined on a certain jet prolongation of a fibered manifold over a one-dimensional base is recalled. The dynamics then can be defined by a distribution (the Euler-Lagrange distribution) which generally is of non-constant rank. This approach leads to a natural geometric definition of regularity and a geometric classification of constrained systems. Since a Lagrangean system is understood as a class of equivalent Lagrangians (which can be of different orders), the theory, including a Hamilton formulation, is independent on the choice of a particular Lagrangian for the Lagrangean system under consideration. Relations to the symplectic, presymplectic, cosymplectic and precosymplectic geometry are discussed.read more

TL;DR: In this article, the foundations of higher order variational sequence theory are explained and relations of the classes in the higher order sequence to basic concepts of the variational calculus on fibered spaces, such as lagrangians, Lepage forms, Euler-Lagrange forms, and Helmholtz-Sonin forms are discussed.

Generalized Hamiltonian dynamics
TL;DR: In this article, the author's procedure for passing from the Lagrangian to the Hamiltonian when the momenta are not independent functions of the velocities is put into a simpler and more practical form, the main results being obtained by a direct solution of the equations provided by consistency requirements.

The Hamilton-Cartan formalism in the calculus of variations
TL;DR: In this paper, Caratheodory, Cartan, and De Donder give an exposition of the geometry of the calculus of variations in several variables, and the main emphasis is on the Hamiltonian formalism via the use of a linear differential form studied in detail by Cartan.
