Zeros of a Two-parameter Family of Harmonic Quadrinomials
Oluma Ararso Alemu, Hunduma Legesse Geleta
In this paper, we determine the numb er of zeros and the zero inclusion regions of a two-parameter family of harmonic quadrinomials. We also determine a curve that separates sense-…

Location of the Zeros of Certain Complex-Valued Harmonic Polynomials
Hunduma L. Geleta, Oluma A. Alemu
Finding an approximate region containing all the zeros of analytic polynomials is a well-studied problem. But the numb er of the zeros and regions containing all the zeros of compl…
