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 ...

A power of a meromorphic function sharing two small functions with a derivative of the power [PDF]

open access: yesMathematica Bohemica, 2022
In connection to a conjecture of W. Lü, Q. Li and C. Yang (2014), we prove a result on small function sharing by a power of a meromorphic function with few poles with a derivative of the power. Our results improve a number of known results.

Meromorphic function sharing a small function with a linear differential polynomial [PDF]

open access: yesMathematica Bohemica, 2016
The problem of uniqueness of an entire or a meromorphic function when it shares a value or a small function with its derivative became popular among the researchers after the work of Rubel and Yang (1977).

The Univalent Function Created by the Meromorphic Functions Where Defined on the Period Lattice [PDF]

open access: yesCommunications in Advanced Mathematical Sciences, 2019
The function $ \xi(z)$ is obtained from the logarithmic derivative function  $\sigma(z)$. The elliptic function $ \wp(z) $ is also derived from the $ \xi(z) $ function.

An Inequality of Meromorphic Vector Functions and Its Application [PDF]

open access: yesAbstract and Applied Analysis, 2011
Firstly, an inequality for vector-valued meromorphic functions is established which extend a corresponding inequality of Milloux for meromorphic scalar-valued function (1946).

On New p-Valent Meromorphic Function Involving Certain Differential and Integral Operators [PDF]

open access: yesAbstract and Applied Analysis, 2014
We define new subclasses of meromorphic p-valent functions by using certain differential operator. Combining the differential operator and certain integral operator, we introduce a general p-valent meromorphic function.

Uniqueness of meromorphic functions sharing one small function

open access: yesJournal of Computational and Applied Mathematics, 2014
In this paper, we study the uniqueness problem of nonlinear differential polynomials of meromorphic functions that share one small function a(z). Our results extend the corresponding result obtained by Zhang et al. (2008)
