Complex zeros of Bessel function derivatives and associated orthogonal polynomials

Seok-Young Chung, Sujin Lee, Young Woong Park

We introduce a sequence of orthogonal polynomials whose associated moments are the Rayleigh-type sums, involving the zeros of the Bessel derivative $J_{ν}^{'}$ of order $ν$ . We also dis…

On the generalized interlacing property for the zeros of Bessel functions

Seok-Young Chung, Sujin Lee, Young Woong Park

This paper investigates a generalized interlacing property between Bessel functions, particularly $J_{ν}$ and $J_{μ}$ , where the difference $∣ ν - μ ∣$ exceeds $2$ . This interlacing phenom…
