色多项式的显示公式

本文利用完全图K_n恰有k个分支S~((n))={K_i∶1≤i≤n}-因子个数N(K_n,k)及第二类Stirling数S(n,k)之间关系,导出图的色多项式的显示公式刻画,并给出几类色多项式及用Stirling数表示的完全i部图的色多项式的显式公式。     

二维递归序列的渐近性

In this paper, we give precise formulas for the general two-dimensional recursion sequences by generating function method, and make use of the multivariate generating functions asymptotic estimation technique to compute their asymptotic values.     

Wey1代数中的消元法及恒等式（英）

In paper [1], Zeilberger presented an approach to special functions identities, besides providing a general mathematical framework for the proof machinery, which leads to mathematically and algorithmically challenging questions such as elimination in noncommutatire operator algebras (Weyl algebra). By the impetus of this approach, we study the elimination under the shift operators.     

一类RNA二级结构的计数

多核苷酸的二级结构可视为一类顶点标号平面图，通常通过枚举每类RNA二级结构图的各种子图来计算其递推公式。本文作者给出了限制端环长度的RNA二级结构的递推公式，并运用隐式估计法计算它的渐近值。
