Abstract:
Starting from the covariant action for gravity, we discuss the BRST quantization of gravity. Taking the chiral gauge the BRST charge has a natural interpretation in terms of the quantum Drinfeld--Sokolov reduction for Sl(3,\re). Nilpotency of this charge leads to the KPZ formula for . In the conformal gauge, where the covariant action reduces to a Toda action, the BRST charge is equivalent to the one recently constructed by Bershadsky et al.- gravitation: induced
