Abstract
A systematic method is presented for processing the equations of motio n of a singular Lagrangian that, in principle, has all dynamical degre es of freedom together with the Lagrangian constraints and a number of identities between the equations of motion. Then, using these identit ies one can find the complete set of gauge transformations of the syst em. Different types of Schwinger model are considered as examples and the related gauge transformations are derived.
