BRST cohomology in Beltrami parametrization
L. Tataru, Ion V. Vancea
Abstract
We study the BRST cohomology within a local conformal Lagrangian field theory model built on a two dimensional Riemann surface with no boundary. We deal with the case of the complex structure parametrized by Beltrami differential and the scalar matter fields. The computation of all elements of the BRST cohomology is given.
