| Abstract: | A duality transformation is investigated for an Ising model in a rectangular lattice with alternate three-spin interactions in the horizontal direction and two-spin interactions in the vertical direction. The partition function is expressed by the one of the nearest-neighbour Ising model under an effective field in the rectangular lattice. It turns out that there is no phase transition in the system. |
