Location of the Zeros of Certain Complex-Valued Harmonic Polynomials

Journal of Mathematics, 2022
Finding the approximate region containing all the zeros of analytic polynomials is a well-studied problem. But the number of the zeros and regions containing all the zeros of complex-valued harmonic polynomials is relatively a fresh research area.

On location in a half-plane of zeros of perturbed first order entire functions [PDF]

Mathematica Moravica, 2019
We consider the entire functions h(z) = X∞ k=0 akz k k! and h~(z) = X∞ k=0 a~kz k k! (a0 = ~a0 = 1; z, ak, a~k ∈ C, k = 1, 2, . . .), provided X∞ k=0 |ak| 2 < ∞, X∞ k=0 |a~k| 2 < ∞ and all the zeros of h(z) are in a half-plane.

The zeros of az2J″ν(z)+bzJ′ν(z)+cJν(z) as functions of order

International Journal of Mathematics and Mathematical Sciences, 1992
If j″νk denotes the kth positive zero of the Bessel function J″ν(x), it has been shown recently by Lorch and Szego [2] that j″ν1 increases with ν in ν>0 and that (with k fixed in 2,3,…) j″νk increases in 00.

Unit circle MVDR beamformer

, 2016
The array polynomial is the z-transform of the array weights for a narrowband planewave beamformer using a uniform linear array (ULA). Evaluating the array polynomial on the unit circle in the complex plane yields the beampattern.

An Improved Analytical Approximation of the Bessel Function J₂(x)

Axioms
In this paper, we derive an analytical and explicit approximation for the Bessel function J2(x) for positive real x with a maximum absolute error of approximately 0.004, which refines some new published analytic approximation.
