Abstract
We study the finite temperature symmetry behaviour of O(N-1) x O(N-2) scalar models on the lattice and we prove that at sufficiently high te mperatures and in arbitrary dimensions their full symmetry is always r estored or, equivalently that the phenomenon of symmetry nonrestoratio n which, according to lowest order perturbation theory, takes place in the continuum version of these models, does not occur on the lattice.
