the Gliozzi-Scherk-Olive (GS0) projection [177]. An alternative light-cone gauge action with manifest spacetime supersymmetry was then proposed by Green and Schwarz [178] and shown by them to be equivalent (by virtue of the triality property of the Spin(8) transverse rotation group) to the light-con

This fact can perhaps be understood most directly by recalling that the effective action is the generating functional for one- particle irreducible Green's functions, which themselves are gauge dependent [28].
