N2 - We modify O(n) models (n>2) in two dimensions so as to comparedifferent thoeries with identical local properties and different global ones. Our O′ (3) model with a particular interaction has vortex-like configuration (π1(P2) = Z2) though it is locally equivalent to an O (3) model (π1(S2) = 0). Our results have been obtained by means of strong coupling methods. The Padé extrapolants show a critical value xc = 11.8.
