RT Book, Section T1 Variational first-order quasilinear equations. A1 Grifone, Joseph A1 Muñoz Masqué, Jaime A1 Pozo Coronado, Luis Miguel A2 Kozma, László A2 Nagy, Péter T. A2 Tamássy, L. AB The systems of first-order quasilinear partial differential equations defined on the 1-jet bundle of a fibred manifold which come from a variational problem defined by an affine Lagrangian are characterized by means of the Hamilton-Cartan formalism and the theory of formal integrability.
