The Unique Range Set of Meromorphic Functions in an Angular Domain [PDF]

open access: yesThe Scientific World Journal, 2014
By using Tsuji's characteristic, we investigate uniqueness of meromorphic functions in an angular domain dealing with the shared set, which is different from the set of the paper (Lin et al., 2006) and obtain a series of results about the unique range ...

A note on the location of poles of meromorphic functions [PDF]

open access: yesJournal of Hyperstructures, 2021
A meromorphic function on an open set D contained in the finite complex plane C is of the form of the ratio betweentwo analytic functions defined on D with denominator not identically zero.

Finiteness of meromorphic functions on an annulus sharing four values regardless of multiplicity [PDF]

open access: yesMathematica Bohemica, 2020
This paper deals with the finiteness problem of meromorphic funtions on an annulus sharing four values regardless of multiplicity. We prove that if three admissible meromorphic functions $f_1$, $f_2$, $f_3$ on an annulus $\mathbb A({R_0})$ share four ...

Extreme problems in the space of meromorphic functions of finite order in the half plane. II

open access: yesМатематичні Студії, 2020
The extremal problems in the space of meromorphic functions of order $\rho>0$ in upper half-plane are studed. The method for studying is based on the theory of Fourier coefficients of meromorphic functions.

Interval estimation on hyper-order of meromorphic solutions of complex linear differential equations with uncertain coefficients

open access: yesApplied Mathematics in Science and Engineering, 2023
The authors address the complex oscillation problems of all solutions of homogenous linear differential equations with meromorphic coefficients. Sufficient conditions for estimating the growth of meromorphic solution with infinite order have been ...

Universal radial limits of meromorphic functions in the unit disk

open access: yesComptes Rendus. Mathématique, 2022
We consider the space of meromorphic functions in the unit disk $\mathbb{D}$ and show that there exists a dense $G_{\delta }$-subset of functions having universal radial limits.
