Abstract
We construct a sequence of new nilpotent BRST charges in the Ramond-Neveu-Schwarz superstring theory based on the hierarchy of found local gauge symmetries. These gauge symmetries are in turn related to global α-symmetries in the space-time forming a noncommutative ring. The constructed BRST charges are presumably connected with the superstring dynamics in a curved space-time with an AdS-type geometry.
