On Harmonic Meromorphic Functions Associated with Basic Hypergeometric Functions [PDF]

open access: yesScientificWorldJournal, 2013
By making use of basic hypergeometric functions, a class of complex harmonic meromorphic functions with positive coefficients is introduced. We obtain some properties such as coefficient inequality, growth theorems, and extreme points.

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 ...

Further Results on Uniqueness of Meromorphic Functions concerning Fixed Points [PDF]

open access: yesAbstract and Applied Analysis, 2014
We will study the uniqueness problems of meromorphic functions of differential polynomials sharing fixed points. Our results improve or generalize some previous results on meromorphic functions sharing fixed points.

Coefficient Estimates for a Subclass of Meromorphic Multivalent q-Close-to-Convex Functions

open access: yesSymmetry, 2021
By making use of the concept of basic (or q-) calculus, many subclasses of analytic and symmetric q-starlike functions have been defined and studied from different viewpoints and perspectives.

Meromorphic functions sharing two sets [PDF]

open access: yes, 2007
summary:In the paper we discuss the uniqueness problem for meromorphic functions that share two sets and prove five theorems which improve and supplement some results earlier given by Yi and Yang [13], Lahiri and Banerjee [5]

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.

On unavoidable families of meromorphic functions

open access: yes, 2021
peer reviewedWe prove several results on unavoidable families of meromorphic functions. For instance, we give new examples of families of cardinality three that are unavoidable with respect to the set of meromorphic functions on $\C$.

Majorization for certain classes of meromorphic functions defined by integral operator [PDF]

open access: yes, 2012
Here we investigate a majorization problem involving starlike meromorphic functions of complex order belonging to a certain subclass of meromorphic univalent functions defined by an integral operator introduced recently by ...

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.
