Master Equation for Lagrangian Gauge Symmetries
R. Banerjee, H. J. Rothe, K. D. Rothe
Using purely Hamiltonian methods we derive a simple differential equation for the generator of the most general local symmetry transformation of a Lagrangian. The restrictions on t…

Hamiltonian Approach to Lagrangian Gauge Symmetries
R. Banerjee, H. J. Rothe, K. D. Rothe
We reconsider the problem of finding all local symmetries of a Lagrangian. Our approach is completely Hamiltonian without any reference to the associated action. We present a simpl…
