Lepage equivalents for second order Lagrangians and applications: modified higher order Boussinesq-type equations
Marcella Palese, Fabrizio Zanello
In the frame of the Lagrangian formalism on -order prolongations of fibered manifolds and related structures such as (prolongation of) projectable vector fields, (sheaves of) di…
A cohomological obstruction in higher dimensional Chern--Simons gauge theories
Marcella Palese, Ekkehart Winterroth
We study a set of cohomology classes which emerge in the cohomological formulations of the calculus of variations as obstructions to the existence of (global) solutions of the Eule…
Geometric integration by parts and Lepage equivalents
Marcella Palese, Olga Rossi, Fabrizio Zanello
We compare the integration by parts of contact forms - leading to the definition of the interior Euler operator - with the so-called canonical splittings of variational morphisms.…
Particle-like, dyx-coaxial and trix-coaxial Lie algebra structures for a multi-dimensional continuous Toda type system
Marcella Palese, Ekkehart Winterroth
We prove that with a -dimensional Toda type system are associated algebraic skeletons which are (compatible assemblings) of particle-like Lie algebras of dyons and triadons…
Symmetry transformations of extremals and higher conserved quantities: invariant Yang--Mills connections
Luca Accornero, Marcella Palese
We characterize symmetry transformations of Lagrangian extremals generating `on shell' conservation laws. We relate symmetry transformations of extremals to Jacobi fields and study…
Higgs fields induced by Yang--Mills type Lagrangians on gauge-natural prolongations of principal bundles
Marcella Palese, Ekkehart Winterroth
We address some new issues concerning spontaneous symmetry breaking. We define classical Higgs fields for gauge-natural invariant Yang--Mills type Lagrangian field theories through…
