Abstract:
The unitarity of BRS-invariant theories is generally guaranteed by the Kugo-Ojima theorem, provided that no BRS single pairs are encountered. It has been conjectured that the appearance of singlet pair would be very exceptional. It is pointed out, however, that its appearance arises in a very simple way in two-dimensional quantum gravity.
