摘要: We derive exact expressions for the excess number of clusters b and cumulants b_n a related quantity at 2-D percolation point. High-accuracy computer simulations are in accord with our predictions. is finite-size correction to Temperley-Lieb or Baxter-Temperley-Ashley formula per site n_c infinite system limit; bn correct bulk cumulants. universal, thus depend only on system's shape. Higher-order corrections show no apparent dependence fractional powers size.
