Higher-order conditions for singular Lagrangian dynamics

X Gracia, J M Pons and N Roman-Roy

Show affiliations


For a kth-order singular Lagrangian the presymplectic equation plus the different 'mth-order differential equation' conditions that can be considered in the Lagrangian space yield different dynamics which are studied. This leads to a new classification of the constraints. This study is also performed in the 'intermediate formalisms' which can be defined between the Lagrangian and the Hamiltonian ones; the corresponding classification schemes are then related.
