摘要：

The author establishes a relation between discrete excitation models at low temperature and the anisotropic rotator, XY and Heisenberg models at high temperature for dimensions D>or=2. The correlation functions of these models are shown to decay exponentially for short-range interactions. A qualitative discussion of the phase transitions is given.
