Decay of correlations for slowly decreasing potentials
Rigorous melts are obtained for the two-point correlations in lattice spin-/sup 1///sub 2/ systems in v-dimensional space for interaction potentials r/sup -s/ (s>0). The ferromagnetic condition is imposed. It is shown that the correlations cannot decay faster than the potential. At low activity o...
