In contrast with a recent formulation, where only BRST invariance holds off shell, two collective sets of fields are introduced and an off-shell realizaiton of the extended algebra in a superspace with two Grassmann coordinates is obtained. The example of the Yang-Mills theory is also considered. \textcopyright{} 1996 The American Physical Society.Read More
