| Abstract: | In this paper, the renormalization group method, based on the work of M.Nauenberg and B.Nienhuis, is used to treat two-dimensional anisotropic triangular Ising system. An approximate solution for the fixed points of the three coupling constants and the critical exponent YT are found in good agreement with the exact solution. |
