| Abstract: | By use of real-space renormalization approach, the phase transition in the one-dimensional Ising system with long-range antiferromagnetic interactions is dicussed. It can be seen from the recurrent equatinn that no phase transition happens at finite temperature in this system, which is quite different from the ferromagnetic case. |
