Complex zeros of Bessel function derivatives and associated orthogonal polynomials

We introduce a sequence of orthogonal polynomials whose associated moments are the Rayleigh-type sums, involving the zeros of the Bessel derivative $J_{\nu }^{\mathrm{\prime }}$ of order $\nu$. We also discuss the fundamental properties of those polynomials such as recurrence, orthogonality, etc. Consequently, we obtain a formula for the Hankel determinant, elements of which are chosen as the aforementioned Rayleigh-type sums. As an application, we complete the Hurwitz-type theorem for $J_{\nu }^{\mathrm{\prime }}$, which deals with the number of complex zeros of $J_{\nu }^{\mathrm{\prime }}$ depending on the range of $\nu$.
