Parler en public c'est un métier . Les intervenants préliminaires auraient dû sous-traiter ! 😅

Bonsoir Monsieur Audin. Système intégrable d’aujourd’hui commençai avec votre étude. Je lirais votre étude. Mais je ne comprends peut-être pas suffisamment pour le thème. Merci.

The symmetry group of the Lagrangian would just be, by the equivalence principle, the diffeomorphism group of the space-time manifold. But because of the standard model piece the symmetry group of this Lagrangian is not just the diffeomorphism group, because the gauge theory has another huge symmetry group which is the group of maps from the manifold to the small gauge group, namely U1×SU2×SU3. Thus, the symmetry group G of the full Lagrangian is neither the diffeomorphism group nor the group of gauge transformations of second kind nor their product, but it is their semi-direct product. It is exactly like what happens with the Poincare group where you have translations and Lorentz transformations, so it is the semi-direct product of these two subgroups
