• #### Order reduction, projectability and constrainsts of second-order field theories and higuer-order mechanics ﻿

(2016-12-01)
Article
Accés obert
The consequences of the projectability of Poincar\'e-Cartan forms in a third-order jet bundle $J^3\pi$ to a lower-order jet bundle are analyzed using the constraint algorithm for the Euler-Lagrange equations in $J^3\pi$. ...
• #### A Hamiltonian study of the stability and bifurcations for the satellite problem ﻿

(2015-10-01)
Article
Accés obert
We study the dynamics of a rigid body in a central gravitational field modeled as a Hamiltonian system with continuous rotational symmetries following the geometric framework of Wang et al. Novelties of our work are the ...
• #### Classification and stability of relative equilibria for the two-body problem in the hyperbolic space of dimension 2 ﻿

(2016-01-13)
Article
Accés restringit per política de l'editorial
We classify and analyze the stability of all relative equilibria for the two-body problem in the hyperbolic space of dimension 2 and we formulate our results in terms of the intrinsic Riemannian data of the problem.

• #### A new multisymplectic unified formalism for second order classical field theories ﻿

(American Institute of Mathematical Sciences, 2015-06-01)
Article
Accés obert
We present a new multisymplectic framework for second-order classical field theories which is based on an extension of the unified LagrangianHamiltonian formalism to these kinds of systems. This model provides a straightforward ...
