Consistent Interactions Between Gauge Fields: The Cohomological Approach

Abstract

The cohomological approach to the problem of consistent interactions between fields with a gauge freedom is reviewed. The role played by the BRST symmetry is explained. Applications to massless vector fields and 2-form gauge fields are surveyed.
