摘要:

在变量$ x_i$中使用扩展方法,该变量$ x_i$出现在$(n-1)$维积分中,该积分表示$n$ -粒子对伊辛平方晶格模型磁化率$χ$的贡献,我们使用$ N^4$多项式时间算法生成3粒子贡献$χ^{(3)}$的长系列系数。我们给出了$χ^{(3)}$的七阶Fuchsian微分方程,它再现了我们的长级数的所有项。本文分析了这类Fuchsian微分方程的性质。

英文摘要:

Using an expansion method in the variables $ x_i$ that appear in the $(n-1)$-dimensional integrals representing the $n$-particle contribution to the Ising square lattice model susceptibility $χ$, we generate a long series of coefficients for the 3-particle contribution $χ^{(3)}$, using a $ N^4$ polynomial time algorithm. We give the Fuchsian differential equation of order seven for $χ^{(3)}$ that reproduces all the terms of our long series. An analysis of the properties of this Fuchsian differential equation is performed.
