Second variational derivative of gauge-natural invariant Lagrangians and conservation laws
M. Francaviglia, M. Palese, E. Winterroth
We consider the second variational derivative of a given gauge-natural invariant Lagrangian taken with respect to (prolongations of) vertical parts of gauge-natural lifts of infini…
A New Geometric Proposal for the Hamiltonian Description of Classical Field Theories
Mauro Francaviglia, Marcella Palese, Ekkehart Winterroth
We consider the geometric formulation of the Hamiltonian formalism for field theory in terms of {\em Hamiltonian connections} and {\em multisymplectic forms}. In this framework the…
Global Generalized Bianchi Identities for Invariant Variational Problems on Gauge-natural Bundles
M. Palese, E. Winterroth
We derive both {\em local} and {\em global} generalized {\em Bianchi identities} for classical Lagrangian field theories on gauge-natural bundles. We show that globally defined gen…
Conservation laws for non global Lagrangians
A. Borowiec, M. Ferraris, M. Francaviglia +1
In the Lagrangian framework for symmetries and conservation laws of field theories, we investigate globality properties of conserved currents associated with non-global Lagrangians…
On a class of polynomial Lagrangians
M. Palese, R. Vitolo
In the framework of finite order variational sequences a new class of Lagrangians arises, namely, \emph{special} Lagrangians. These Lagrangians are the horizontalization of forms o…
