3. Although the amplitude of these fluctuations is bounded in 3D structures ( even in the limit of infinite size ), the Mermin Wagner theorem shows that the amplitude of long-wavelength fluctuations grows logarithmically with the scale of a 2D structure, and would therefore be unbounded in structures of infinite size.
4. The Mermin Wagner theorem prevents any spontaneous symmetry breaking of the model's continuous ( internal ) symmetry on a spatial lattice of dimension, i . e . the ( spin-) field's expectation value remains zero for any " finite " temperature ( quantum phase transitions remain unaffected ).
