摘要:

本文讨论了六粒子对正方格子伊辛模型磁化率的贡献$\tildeχ^{(6)}$。我们已经生成了$\tildeχ^{(6)}$的模素数级数系数。级数的长度足以产生相应的Fuchsian线性微分方程(模素数)。我们得到的Fuchsian线性微分方程的零化的“耗尽”系列$Φ^{(6)}=\tildeχ^{(6)} - {2 \over 3} \tildeχ^{(4)} + {2 \over 45} \tildeχ^{(2)}$。相应的微分算子的因式分解是使用在以前的论文中介绍的因式分解模素数的方法进行的。“耗尽”微分算子具有类似于$\tildeχ^{(5)}$的相应算子的结构。它分裂成更小阶的因子,最左边的六阶因子相当于对应于椭圆积分$E$的线性微分算子的对称五次幂。最右边的因子具有直和结构,并且使用模多个素数的级数计算,直和中的所有因子都以精确的算术重构。

英文摘要:

This paper deals with $\tildeχ^{(6)}$, the six-particle contribution to the magnetic susceptibility of the square lattice Ising model. We have generated, modulo a prime, series coefficients for $\tildeχ^{(6)}$. The length of the series is sufficient to produce the corresponding Fuchsian linear differential equation (modulo a prime). We obtain the Fuchsian linear differential equation that annihilates the "depleted" series $Φ^{(6)}=\tildeχ^{(6)} - {2 \over 3} \tildeχ^{(4)} + {2 \over 45} \tildeχ^{(2)}$. The factorization of the corresponding differential operator is performed using a method of factorization modulo a prime introduced in a previous paper. The "depleted" differential operator is shown to have a structure similar to the corresponding operator for $\tildeχ^{(5)}$. It splits into factors of smaller orders, with the left-most factor of order six being equivalent to the symmetric fifth power of the linear differential operator corresponding to the elliptic integral $E$. The right-most factor has a direct sum structure, and using series calculated modulo several primes, all the factors in the direct sum have been reconstructed in exact arithmetics.
