Field equations or conservation laws?
Mauro Francaviglia, Marcella Palese, Ekkehart Winterroth
We explicate some epistemological implications of stationary principles and in particular of Noether Theorems. Noether's contribution to the problem of covariance, in fact, is epis…
Cohomological obstructions in locally variational field theories
M. Francaviglia, M. Palese, E. Winterroth
We study cohomological obstructions to the existence of global conserved quantities. In particular, we show that, if a given local variational problem is supposed to admit global s…
Higher-Order Gauss-Bonnet Cosmology
Salvatore Capozziello, Mauro Francaviglia, Andrey N. Makarenko
We study cosmological models derived from higher-order Gauss-Bonnet gravity by using the Lagrange multiplier approach without assuming the presence of additional fields wi…
Mathematical Equivalence vs. Physical Equivalence between Extended Theories of Gravitations
L. Fatibene, M. Francaviglia
We shall show that although Palatini f(R)-theories are equivalent to Brans-Dicke theories, still the first pass the Mercury precession of perihelia test, while the second do not. W…
Do Barbero-Immirzi connections exist in different dimensions and signatures?
L. Fatibene, M. Francaviglia, S. Garruto
We shall show that no reductive splitting of the spin group exists in dimension 3 \leq m \leq 20 other than in dimension m = 4. In dimension 4 there are reductive splittings in any…
Dynamics And Thermodynamics Of Blackholes And Naked Singularities II
Lorenzo Fatibene, Mauro Francaviglia, Roberto Giambò +1
Proceedings of the second edition of the international Workshop "Dynamics and Thermodynamics of Blackholes and Naked Singularities" (Department of Mathematics of the Politecnico of…
