Pseudogroups of symmetries and Morita equivalences
Luca Accornero, Francesco Cattafi
This work is a spin-off of an on-going programme which aims at revisiting the original studies of Lie and Cartan on pseudogroups and geometric structures from a modern perspective.…

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…
