Hamiltonian Approach to Lagrangian Gauge Symmetries
R. Banerjee, H. J. Rothe, K. D. Rothe
Abstract
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 simple algorithm for obtaining the restrictions on the gauge parameters entering in the definition of the generator of gauge transformations.
