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-…
Topological and dynamical properties of composition operators
Tesfa Mengestie, Werkaferahu Seyoum
We study various properties of composition operators acting between generalized Fock spaces and with weight functions grow faster than the c…
Zeros of a certain class of Gauss hypergeometric polynomials
Addisalem Abathun, Rikard Bøgvad
In this paper, we give results that partially prove a conjecture which was discussed in our previous work (arXiv:1307.4991). More precisely, we prove that as the zer…
Asymptotic distribution of zeros of a certain class of hypergeometric polynomials
Addisalem Abathun, Rikard Bøgvad
We study the weak asymptotic behavior of the zeros of a family of a certain class of (generalized) hypergeometric polynomials, using the associated hypergeometric differential equa…
