| Abstract: | The critical exponents of the triangular lattice Ising model with long-range interactions γ-s are calculated by the real space renormalization group. Using the simplest Kadanoff blocks and the lowest approximation of cumulant expansion, it is shown that there exists a finite critical temperature when 4(1 - ㏑2/㏑3) < s < 4. |
