Abstract
The ground-state structures (T=0) for a class of Ising model with extended-range interactions are determined. It is shown that the ground states may be obtained in a very general way for all values of the coupling parameters and in all dimensions. A distinction is made between one- and multiple-magnetization phases. It is seen that inclusion of only a few types of near neighbors is not sufficient to produce the added complexity of the multiple-magnetization phases among the ground states.Keywords
