摘要: Abstract We investigate the variation of string field action under changes vertices giving rise to different decompositions moduli spaces Riemann surfaces. establish that any such change in arises from a transformation canonical with respect Batalin-Vilkovisky (BV) antibracket and find explicit form generator infinitesimal transformations. Two theories using space are shown yield same gauge-fixed upon use gauge-fixing conditions. also elaborate on recent work covariant BV formalism, emphasize necessity measure two-dimensional order extend analysis background independence quantum theory.
