Bessel函数阶导数的反射公式

Reflection formulas for order derivatives of Bessel functions

J. L. González-Santander

摘要:

从贝塞尔函数的$n$阶导数关于阶的新整表示出发,导出了整数阶的$J_{ν}\left( t\right) $和$% Y_{ν}\left( t\right) $的一阶和二阶导数以及任意实数阶的$I_{ν}\left( t\right) $和$K_{ν}\left( t\right) $的$n$阶导数的反射公式.作为一阶导数反射公式的应用,我们将文献中的一些公式推广到负整数阶。此外,作为一个副产品,我们计算的积分,这似乎是没有在文献中报道。

英文摘要:

From new integral representations of the $n$-th derivative of Bessel functions with respect to the order, we derive some reflection formulas for the first and second order derivative of $J_{ν}\left( t\right) $ and $% Y_{ν}\left( t\right) $ for integral order, and for the $n$-th order derivative of $I_{ν}\left( t\right) $ and $K_{ν}\left( t\right) $ for arbitrary real order. As an application of the reflection formulas obtained for the first order derivative, we extend some formulas given in the literature to negative integral order. Also, as a by-product, we calculate an integral which does not seem to be reported in the literature.
