Árpád Baricz, Pál A. Kupán, Róbert Szász

摘要:

本文的目的是确定第一类贝塞尔函数在三种不同归一化条件下的星形半径。在证明我们的主要结果的关键工具是第一类贝塞尔函数的Mittag-Leffler展开和事实,即根据Ismail和Muldoon [IM 2],一些Dini函数的最小正零点小于第一类贝塞尔函数的第一个正零点。

英文摘要:

In this note our aim is to determine the radius of starlikeness of the normalized Bessel functions of the first kind for three different kinds of normalization. The key tool in the proof of our main result is the Mittag-Leffler expansion for Bessel functions of the first kind and the fact that, according to Ismail and Muldoon [IM2], the smallest positive zeros of some Dini functions are less than the first positive zero of the Bessel function of the first kind.
