Shift-invariant spaces on finite undirected graphs
Yang Chen, Seok-Young Chung, Qiyu Sun
Shift-invariant spaces (SISs) on the real line provide a natural framework for representing, analyzing and processing signals with inherent shift-invariant structure. In this paper…
Partial fraction expansions and zeros of Hankel transforms
Yong-Kum Cho, Seok-Young Chung, Young Woong Park
It is proved by the method of partial fraction expansions and Sturm's oscillation theory that the zeros of certain Hankel transforms are all real and distributed regularly between…
Uniform bounds, zero separation and monotonicity for the regular Coulomb wave functions
Seok-Young Chung
This paper begins by deriving the uniform bounds for the regular Coulomb wave function and its derivative . We then examine detailed zero configurations…
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 of order . We also d…
