修正Bessel函数比的一类新的锐界

A new type of sharp bounds for ratios of modified Bessel functions

D. Ruiz-Antolin, J. Segura

摘要:

连续阶第一类和第二类修正Bessel函数之比的界是大量科学应用中出现的重要量。我们得到新的界限,这是准确的参数在一个大的区域,这是形状比以前的界限。新的界限得到的Riccati方程满足这些比率的定性分析。一个程序被认为是从Riccati方程的分析得到的边界被用来定义一个新的函数,满足一个新的Riccati方程,产生更清晰的边界。类似的想法可以应用于其他功能。

英文摘要:

The bounds for the ratios of first and second kind modified Bessel functions of consecutive orders are important quantities appearing in a large number of scientific applications. We obtain new bounds which are accurate in a large region of parameters and which are shaper than previous bounds. The new bounds are obtained by a qualitative analysis of the Riccati equation satisfied by these ratios. A procedure is considered in which the bounds obtained from the analysis of the Riccati equation are used to define a new function satisfying a new Riccati equation which yields sharper bounds. Similar ideas can be applied to other functions.
