Abstract: (Elsevier)
Generalizations of the non-linear σ-model and of the CP N model are considered. They are invariant under a global group G and under a local gauge subgroup H. Whenever G/H defines a symmetric space, we can show that these models are asymptotically free. Furthermore, in two dimensions the local gauge invariance leads to confinement.- FIELD THEORETICAL MODEL: SIGMA
