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…
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…
The First Law of Isolated Horizons via Noether Theorem
G. Allemandi, M. Francaviglia, M. Raiteri
A general recipe proposed elsewhere to define, via Noether theorem, the variation of energy for a natural field theory is applied to Einstein-Maxwell theory. The electromagnetic fi…
Fourth-Order Ricci Gravity
A. Borowiec, M. Francaviglia, V. I. Smirichinski
The Euler-Lagrange equations of motion for the most general Ricci type gravitational Lagrangians are derived by means of a purely metric formalism.
