Lagrangian Functions Which Determine a Symmetrical Tensor by Schrodinger's Rule
The choice of a Lagrangian function to be used in a variational principle may be limited by the condition that the tensor derived from it by Schrodinger’s rule shall be symmetrical. To meet this condition the function must satisfy a certain set of partial differential equations. Particular and gen...
