Representations of the ghost canonical commutation relations and nilpotency of the BRST charge in string theory

It is shown that the nilpotency of the string BRST charge at the quantum level implies constraints on the possible representations of the ghost canonical commutation relations. This is true for both the bosonic and fermionic (NSR) string models.On montre que la charge BRST quantique n'est nilpotente que pour certaines représentations des relations de commutation des champs fantômes. Cette propriété est illustrée dans le cas des modèles de cordes.Henneaux Marc, Fisch Jean.
