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.
- BRST = quantization procedure of a classical system with constraints by introducing odd variables (“ghosts”)
- 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
\Lambda_{\infty} semi-infinite form
\mathfrak{g} : \mathbb{Z}-graded Lie algebra
\sigma : anti-linear automorphism sending \mathfrak{g}_{n} to \mathfrak{g}_{-n}
H^2(\mathfrak{g})=0 (i.e. no non-trivial central extension)
ghost variables
