查询词典 polynomial

In this paper, we discuss some recurrence relations and congruence properties of Bell polynomial, and give a class of recurrence relations satisfied by GSN pairs. Furthermore, we givethe definition of extended GSN pairs Gand G, so we unify the binomial coefficients, Gaussian coefficients, and Stirling numbers. We provide urn ,models for G(n,k|w,0) andG(n,k|0,w).

在这篇论文中，我们讨论了Bell多项式中的递归关系和同余问题，给出了广义Stirling数对的一类递归关系式，提出了扩展的GSN对G和G的概念，统一了二项式系数、高斯系数和Stirling数，并利用模型对G和G进行了组合解释。
