摘要
利用二项式系数的性质,本文讨论了含有幂与指数函数的两类组合和: 与.得到了它们的递推关系以及一般表达式.
By applying some properties of binomial coefficients, the purpose of this paper is to discuss two kinds of Combinatorial sums involving power and exponent functions: Sm,n(x)=^∞∑k=0(^n k)k^m x^k与Tm,n(x)=^∞∑k=0(^(n+k) k)k^m x^k(m,n,k∈N,x∈ C).Their recurrence relations and representation formulas are obtained.
