Gauge Invariance, BRST Invariance, and Ward Identities, in String Field Theory

  • S. P. de Alwis
Part of the NATO ASI Series book series (NSSB, volume 175)


The derivation of Ward identities from BRST invariant gauge fixed versions of string field theory is discussed for both open and closed strings. However, in the latter case some problems are encountered in attempting to justify the gauge fixed action by the Batalin Vilkovisky method.
