psi函数与调和数的尖锐不等式

Sharp inequalities for the psi function and harmonic numbers

Feng Qi, Bai-Ni Guo

摘要:

本文分别建立了关于psi函数$ψ$与调和数$H_n$的界的两个尖锐不等式,推广了[I. Muqattash和M. Yahdi,\textit{Infinite family of approximations of the Digamma function},Math. Comput.建模\textbf{43}(2006),1329 \nobreakdash --1336。]并给出了一些说明。

英文摘要:

In this paper, two sharp inequalities for bounding the psi function $ψ$ and the harmonic numbers $H_n$ are established respectively, some results in [I. Muqattash and M. Yahdi, \textit{Infinite family of approximations of the Digamma function}, Math. Comput. Modelling \textbf{43} (2006), 1329\nobreakdash--1336.] are improved, and some remarks are given.
