用保角自举法讨论了支化聚合物模型和随机场Ising模型（RFIM）的降维问题。用小次元对这两种模型的尺度尺度进行了评价，并将结果分别与ed Yang-Lee边缘奇点和纯Ising模型进行了比较。对于前一种情况，降维证明是有效的，对于后一种情况，与降维的偏差可以在五个维度以下看到。
Dimensional reductions in the branched polymer model and the random field Ising model (RFIM) are discussed by a conformal bootstrap method. Small minors are applied for the evaluations of the scale dimensions of these two models and the results are compared to theD Yang–Lee edge singularity and to the pureD Ising model, respectively. For the former case, the dimensional reduction is shown to be valid forand, for the latter case, the deviation from the dimensional reduction can be seen below five dimensions.
