Special Issue Information

Dear Colleagues,

We have the intention of launching a Special Issue of Axioms. The central topic of this Special Issue will be “Geometric, Value-Sharing and Asymptotic Properties of Analytic and Meromorphic Functions”. We would give an opportunity to showcase recent contributions in the many branches of both theoretical and practical studies in the theory of analytic and meromorphic functions of one and several complex variables. The geometric, value-sharing, and asymptotic properties of these functions are useful in many branches of mathematics, including algebraic geometry, number theory, analytic combinatorics, applied mathematics, approximation theory, ordinary and partial differential equations, and their systems.

This Special Issue delves into the intricate characteristics of analytic and meromorphic functions, forming a cornerstone of complex analysis. The primary objective is to comprehensively investigate three fundamental aspects of these functions: their geometric behavior, value-sharing phenomena, and asymptotic properties. In the realm of geometric function theory, the study focuses on properties such as univalence, starlikeness, and convexity, often exploring mapping properties defined by these functions. This includes analyzing distortion theorems and coefficient estimates for various subclasses of analytic functions. The investigation into value-sharing employs methods from the Nevanlinna theory to understand how meromorphic functions and their derivatives relate through shared values or sets. This part aims to establish new uniqueness theorems and explore the implications of functions sharing specific configurations of values. Concurrently, the asymptotic analysis examines the growth rates and limiting behavior of these functions as the independent variable approaches boundary points or infinity. This involves studying concepts like the generalized or modified order and type of entire and meromorphic functions, as well as the distribution of their asymptotic values. This Special Issue will attempt to reveal deeper connections and interplay between these geometric, value distribution, and asymptotic characteristics. By synthesizing results from these interconnected areas, our Special Issue contributes to a more profound understanding of the complex structures and behaviors inherent in analytic and meromorphic function theory.

In the hopes that this initiative is of interest, we encourage you to submit your current original research paper to be included in this Special Issue.

This Special Issue is a continuation of three previous successful issues:

In this paper, certain subclasses of meromorphic harmonic functions which are formulated using a q-differential operator are meticulously analyzed. Initially, two new subclasses WHq(k;E,F) and Wηq(k;E,F) associated with the Janowski function with relevance to the idea of weak subordination are defined. These classes are further studied through their various analytical and geometric properties. Some of these explored properties include the necessary and sufficient coefficient condition, the radii of starlikeness, characterizations of extreme points, distortion estimation, closeness under convolution, and convex combination features. Additionally, the asymptotic behavior of the coefficients is also examined, and to express the findings, the Big-O, little-o, and asymptotic equivalency notations are used. These findings significantly represent the interaction between the growth, dominant terms, and limiting behavior of functions within these subclasses. Full article

Abstract
The paper provides a new approach to estimating the coefficients of arbitrary holomorphic functions, which still remains an important problem of complex analysis. This approach is intrinsically connected with the features of univalent functions and with Teichmüller spaces. Full article
