Название: Boundary conditions and cluster property in two-dimensional Ising ferromagnets
Автор: Merlini D.
Аннотация:
Using the Sherman theorem on paths, the cluster property, and the second GKS inequality, we obtain some results in favor of the nonexistence of non-translation-invariant equilibrium states for twodimensional Ising models with ferromagnetic short-range interactions in the low-temperature region.
