Value distribution for difference operator of meromorphic functions with maximal deficiency sum

open access: yesJournal of Inequalities and Applications, 2013
The main purpose of this paper is to investigate the relationship between the characteristic function of a meromorphic function f(z) with maximal deficiency sum and that of the exact difference Δcf=f(z+c)−f(z).

Meromorphic traveling wave solutions of the complex cubic-quintic Ginzburg-Landau equation [PDF]

open access: yes, 2012
We look for singlevalued solutions of the squared modulus M of the traveling wave reduction of the complex cubic-quintic Ginzburg-Landau equation. Using Clunie's lemma, we first prove that any meromorphic solution M is necessarily elliptic or degenerate ...

Uniqueness theorems related to weighted sharing of two sets

open access: yesActa Universitatis Sapientiae: Mathematica, 2018
Using the notion of weighted sharing of sets, we study the uniqueness problem of meromorphic functions sharing two finite sets. Our results are inspired from an article due to J. F. Chen (Open Math., 15 (2017), 1244–1250).

Uniqueness of meromorphic functions sharing two values

open access: yesJournal of Inequalities and Applications, 2012
In this article, we shall study the uniqueness problems on meromorphic functions sharing nonzero finite value or having fixed points. Our results extend the corresponding results of Fang and Hua, Yang and Hua, and Fang and Qiu. MSC 2010: 30D35, 30D30.

Differential polynomials of L-functions with truncated shared values

open access: yesOpen Mathematics, 2019
In this paper, by using the idea of truncated counting functions, we study the uniqueness of transcendental meromorphic functions and L-functions whose certain nonlinear differential polynomials share one finite nonzero value.

Some results on q-difference equations

open access: yesAdvances in Differential Equations, 2012
In this paper, we consider the q-difference analogue of the Clunie theorem. We obtain there is no zero-order entire solution of fn(z)+(∇qf(z))n=1 when n≥2; there is no zero-order transcendental entire solution of fn(z)+P(z)(∇qf(z))m=Q(z) when n>m≥0; and ...

Uniqueness theorems for L-functions in the extended Selberg class

open access: yesOpen Mathematics, 2018
In this paper, we obtain uniqueness theorems of L-functions from the extended Selberg class, which generalize and complement some recent results due to Li, Wu-Hu, and Yuan-Li-Yi.
