-Take note that this procedure of modding out $\mathcal G$ from $\mathcal A$ is what leads to [[theories:​quantum_theory:​quantum_field_theory:​ghosts|Ghosts]]. To do this properly requires to make use of the [[advanced_tools:​gauge_symmetry:​brst|BRST]] formalism. ​+Take note that this procedure of modding out $\mathcal G$ from $\mathcal A$ is what leads to [[advanced_notions:​quantum_field_theory:​ghosts|Ghosts]].
