A note on zeros of derivatives of ultraspherical Bessel functions

Tao Jiang

For any fixed $I^½ \geq 0, I^´ \in R$ and $x > 0$ , we investigate the positive zeros of the derivatives $j_{I^½, I^´}^{'} (x)$ and $y_{I^½, I^´}^{'} (x)$ , where \begin{equation*} j_{Î½,Î´}(x)=x…

Bessel functions and Weyl's law for balls and spherical shells

Jingwei Guo, Tao Jiang, Zuoqin Wang +1

The purpose of this paper is twofold. One is to investigate the properties of the zeros of cross-products of Bessel functions or derivatives of ultraspherical Bessel functions, as…
