Unified formalism for non-autonomous mechanical systems
(AIP, 2008-06-01)
Working paper
Accés obertWe present a unified geometric framework for describing both the Lagrangian and Hamiltonian formalisms of regular and non-regular time-dependent mechanical systems, which is based on the approach of Skinner and Rusk (1983). ... -
Constraint algorithm for k-presymplectic Hamiltonian systems. Application to singular field theories
(2009-03-10)
Working paper
Accés obertThe k-symplectic formulation of field theories is especially simple, since only tangent and cotangent bundles are needed in its description. Its defining elements show a close relationship with those in the symplectic ...
