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…

Towers with skeletons for the (2+1)-dimensional continuous isotropic Heisenberg spin model
Marcella Palese
We associate a tower with an infinitesimal algebraic skeleton to the (2+1)-dimensional (compact and noncompact) Heisenberg spin model. In particular, we construct the absolute para…
