Abstract
We quantize the BRS gauge field theory canonically and prove that it is equivalent to the theory in the physical gauge without resorting to perturbation theory. The relationship between the quantum states in the BRS theory and those in the physical theory is explicitly given. We also show that one may obtain matrix elements of gauge-invariant operators in the physical theory by calculating corresponding ones in the BRS theory.
