Gauge Theories: Geometry and cohomological invariants

M. Kachkachi, A. Lamine, M. Sarih

We develop a geometrical structure of the manifolds $\Gamma$ and $\hat{\Gamma }$ associated respectively to the gauge symmetry and to the BRST symmetry. Then, we show that ($\hat{\Gamma },\hat{\zeta },\Gamma$), wh…
