A new multisymplectic unified formalism for second order classical field theories
(American Institute of Mathematical Sciences, 2015-06-01)
Article
Accés obertWe 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 ... -
Variational principles for multisymplectic second-order classical field theories
(2015-09-01)
Article
Accés obertWe state a unified geometrical version of the variational principles for second-order classical field theories. The standard Lagrangian and Hamiltonian variational principles and the corresponding field equations are ... -
Reduction of polysymplectic manifolds
(2015-02-06)
Article
Accés obertThe aim of this paper is to generalize the classical Marsden-Weinstein reduction procedure for symplectic manifolds to polysymplectic manifolds in order to obtain quotient manifolds which inherit the polysymplectic structure. ... -
Unified formalism for the generalized kth-order Hamilton-Jacobi problem
(2014-10-01)
Article
Accés obertThe geometric formulation of the Hamilton-Jacobi theory enables us to generalize it to systems of higher-order ordinary differential equations. In this work we introduce the unified Lagrangian-Hamiltonian formalism for the ... -
Geometric Hamilton-Jacobi theory for higher-order autonomous systems
(2014-06-13)
Article
Accés restringit per política de l'editorialThe geometric framework for the Hamilton-Jacobi theory is used to study this theory in the background of higher-order mechanical systems, in both the Lagrangian and Hamiltonian formalisms. Thus, we state the corresponding ... -
Higher-order mechanics: variational principles and other topics
(American Institute of Mathematical Sciences, 2013-12)
Article
Accés obertAfter reviewing the Lagrangian-Hamiltonian unified formalism (i.e, the Skinner-Rusk formalism) for higher-order (non-autonomous) dynamical systems, we state a unified geometrical version of the Variational Principles which ...
