Scale symmetry reduction applied to singular Lagrangians via De-Donder-Weyl formalism yields equivalent frictional dynamics for particles and fields, with applications to general relativity.
A review presents the geometry of pre-symplectic and pre-contact manifolds and develops constraint algorithms for admissible phase space in Hamiltonian systems with degeneracies.
