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…
