Variational Principles for Natural Divergence-free Tensors in Metric Field Theories
Ian M. Anderson, Juha Pohjanpelto
Let be a system of differential equations for the components of a metric tensor on . Suppose that transforms tensorially under the action of the dif…
Persistence of Freeness for Lie Pseudogroup Actions
Peter Olver, Juha Pohjanpelto
The action of a Lie pseudogroup on a smooth manifold induces a prolonged pseudogroup action on the jet spaces of submanifolds of . We prove in this paper that both…
Generalized Symmetries of Massless Free Fields on Minkowski Space
Juha Pohjanpelto, Stephen C. Anco
A complete and explicit classification of generalized, or local, symmetries of massless free fields of spin is carried out. Up to equivalence, these are found to consi…
Symmetries and currents of massless neutrino fields, electromagnetic and graviton fields
Stephen C. Anco, Juha Pohjanpelto
A recent complete, explicit classification of all locally constructed symmetries and currents for free spinorial massless spin s fields on Minkowski space is summarized and extende…
Conserved currents of massless fields of spin s>0
Stephen C. Anco, Juha Pohjanpelto
A complete and explicit classification of all locally constructed conserved currents and underlying conserved tensors is obtained for massless linear symmetric spinor fields of any…
Classification of generalized symmetries of the Yang-Mills fields with a semi-simple structure group
Juha Pohjanpelto
A complete classification of generalized symmetries of the Yang-Mills equations on Minkowski space with a semi-simple structure group is carried out. It is shown that any generaliz…
