Conservation Laws and Variational Sequences in Gauge-Natural Theories
L. Fatibene, M. Francaviglia, M. Palese
In the classical Lagrangian approach to conservation laws of gauge-natural field theories a suitable (vector) density is known to generate the so--called {\em conserved Noether cur…
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…
On-shell symmetries
L. Fatibene, M. Ferraris, M. Francaviglia
We define on-shell symmetries and characterize them for Lagrangian systems. The terms appearing in the variation of the Poincare'-Cartan form, which vanish because of field equatio…
Charges and Energy in Chern-Simons Theories and Lovelock Gravity
G. Allemandi, M. Francaviglia, M. Raiteri
Starting from the SO(2,2n) Chern-Simons form in (2n+1) dimensions we calculate the variation of conserved quantities in Lovelock gravity and Lovelock-Maxwell gravity through the co…
Conserved Quantities from the Equations of Motion (with applications to natural and gauge natural theories of gravitation)
M. Ferraris, M. Francaviglia, M. Raiteri
We present an alternative field theoretical approach to the definition of conserved quantities, based directly on the field equations content of a Lagrangian theory (in the standar…
A covariant formalism for Chern-Simons gravity
A. Borowiec, M. Ferraris, M. Francaviglia
Chern--Simons type Lagrangians in dimensions are analyzed from the point of view of their covariance and globality. We use the transgression formula to find out a new fully c…
Remarks on the Entropy of Non-Stationary Black Holes
G. Allemandi, L. Fatibene, M. Francaviglia
The definition of entropy obtained for stationary black holes is extended in this paper to the case of non-stationary black holes. Entropy is defined as a macroscopical thermodynam…
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…
