| Abstract: | A collection of upper bounds on the magnetization in ferromagnetic one-component spin systems is derived from generalizations of the mean-field approximation. In particular, it contains sequences of bounds that converge to the true magnetization. The spin systems in question satisfy the GHS-inequality.Institut für Theoretische Physik, Universität Zürich, Zürich, Switzerland |
