Gi-Sang Cheon, Tamás Forgács, Hana Kim, Khang Tran

摘要:

我们提出的组合和分析结果Sheffer序列的生成函数的形式$G(x,z)=Q(z)^{x}Q(-z)^{1-x}$,其中$Q$是一个二次多项式的实零点。通过使用Riordan矩阵的性质,我们解决组合的性质和解释我们的谢弗序列的多项式及其系数。我们还证明了除了两个例外的零点,在这样的Sheffer序列的多项式具有足够大的次数位于线$x=1/2+it$的零点。

英文摘要:

We present combinatorial and analytical results concerning a Sheffer sequence with a generating function of the form $G(x,z)=Q(z)^{x}Q(-z)^{1-x}$, where $Q$ is a quadratic polynomial with real zeros. By using the properties of Riordan matrices we address combinatorial properties and interpretations of our Sheffer sequence of polynomials and their coefficients. We also show that apart from two exceptional zeros, the zeros of polynomials with large enough degree in such a Sheffer sequence lie on the line $x=1/2+it$.
