Thermal fluctuations are important for amphiphihc bilayer membranes since typical bending stifInesses can be a few kBT The rod-like constituent molecules are generically tilted with respect to the local normal for packing reasons We study the effects of fluctuations on membranes with nematic order, a simplified idealization with the same novel features as realistic tilt order We find that nematic membranes lie m the same universality class as hexatic membranes, i-e the couplings that distinguish nematic from hexatic order are marginally irrelevant Our calculation also illustrates the advantages of conformal gauge, which brings great conceptual and technical simplifications compared to the more popular Monge gauge
