introduction
  • Gauge theory = principal G-bundle
  • We require a quantization of gauge theory.
  • BRST quantization is one way to quantize the theory and is a part of path integral.
  • Gauge theory allows 'local symmetry' which should be ignored to be physical. 
  • This ignoring process leads to the cohomoloy theory.
  • the conditions D = 26 and α0 = 1 for the space-time dimension D and the zero-intercept α0 of leading trajectory are required by the nilpotency QB2 = 0 of the BRS charge
