Lagrangian and Multisymplectic Descriptions of Classical Fields: A Connection in the Momentum Representation
José Francisco Pérez-Barragán
The multisymplectic Hamiltonian formalism is a generalization of the Hamiltonian formalism that manifestly preserves covariance in the description of fields and that has been propo…

Generation of Standing Waves on a Real String
José Francisco Pérez-Barragán
We investigate the generation of standing waves in the model provided by the inhomogeneous telegraph equation under different forcing conditions. We show that sustained standing wa…

Unified Lorentz-covariant Poisson Bracket for the Electrodynamics of a Point Particle
José Francisco Pérez-Barragán
Using the multisymplectic Hamiltonian formalism, we propose a Poisson bracket for the electromagnetic field that, in addition to satisfying the restricted principle of relativity,…
