本文考虑一类涉及贝塞尔函数的和在方阵上的求和。这些和涉及位于中心晶胞内的任意向量的长度(λ)。我们建立的条件下,减少到多项式形式的总和(可能有一个单一的对数项,此外),并显示这些多项式可以方便地评估。
We consider a class of sums involving Bessel functions summed over the square array. The sums involve the length (ξ) of an arbitrary vector lying within the central unit cell. We establish conditions under which the sums reduce to polynomial forms in ξ (possibly with a single logarithmic term in addition), and show how these polynomials may be conveniently evaluated.
