More on Boundary Behavior of Univalent Harmonic Mappings
Gebreslassie atsbha weldegebrial, hunduma legesse geleta
Many authors have examined various boundary behaviors of injective harmonic mappings in the open unit disk. Building on Laugesen's work, Bshouty and others explored the boundary be…
The Image of Critical Circle and Zero-free Curve for Quadrinomials
Oluma Ararso Alemu, Hunduma Legesse Geleta
The location of the zeros of a two-parameter family of complex-valued harmonic quadrinomials depends on the parameters. In this paper, we determine and demonstrate that the image o…
More Zero-Free Regions for Fractional Hypergeometric Zeta Functions
Demessie Ergabus Birmechu, Hunduma Legesse Geleta
Some zero-free regions were known on the right half of the complex plane in the form of vertical strips for fractional hypergeometric zeta functions. In this paper, we describe and…
