Abstract
Exploiting the path-dependence of the gauge-invariant variables formal ism, we illustrate how the gauge-fixing procedure correspond, in this formalism, to choose the path. In particular, we consider two propagat ors for the gauge field. QED is formulated in terms of gauge-invariant variables and its quantization is carried out using the Dirac's metho d for constrained systems.
