Field-theory models that admit alternative Lagrangian formulations. I
F. A. Lunev
Abstract:
Some theorems are proved concerning the structure of Lagrangian systems
of differential equations for which the Lagrangian is not uniquely determined. In particular, a complete description is obtained for bi-Lagrangian systems of second order with hyperregular Lagrangians quadratic in the derivatives.
