Apostol-Bernoulli和Apostol-欧拉多项式的渐近估计

Asymptotic estimates for Apostol-Bernoulli and Apostol-Euler polynomials

Luis M. Navas, Francisco J. Ruiz, Juan L. Varona

摘要:

详细分析了伯努利多项式$\mathcal{B}_{n}(x;λ)$的渐近性态.起点是他们的傅里叶级数的$[0,1]$,它示出,仍然有效的渐近展开在紧凑的子集的复平面。这是用来确定明确的估计常数的近似,并分析振荡现象,在某些情况下出现。这些结果被转移到Apostol-欧拉多项式$\mathcal{E}_{n}(x;λ)$通过一个简单的关系连接到Apostol-伯努利多项式。

英文摘要:

We analyze the asymptotic behavior of the Apostol-Bernoulli polynomials $\mathcal{B}_{n}(x;λ)$ in detail. The starting point is their Fourier series on $[0,1]$ which, it is shown, remains valid as an asymptotic expansion over compact subsets of the complex plane. This is used to determine explicit estimates on the constants in the approximation, and also to analyze oscillatory phenomena which arise in certain cases. These results are transferred to the Apostol-Euler polynomials $\mathcal{E}_{n}(x;λ)$ via a simple relation linking them to the Apostol-Bernoulli polynomials.
