dc.descriptionAfter some recalls on the standard (non)-linear $σ$ model, we discuss the interest of B.R.S. symmetry in non-linear $σ$ models renormalisation. We also emphasise the importance of a correct definition of a theory through physical constraints rather than as given by a particular Lagrangian and discuss some ways to enlarge the notion of renormalisability.
