A note on an extension of Lindelöf's theorem to meromorphic functions

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1983
S. M. Shah [3] has given an extension of Lindelöf's Theorem to meromorphic functions. He also obtained an expression for the characteristic function of a meromorphic function of integer order.

Rational maps with real multipliers [PDF]

open access: yes, 2009
Let f be a rational function such that the multipliers of all repelling periodic points are real. We prove that the Julia set of such a function belongs to a circle. Combining this with a result of Fatou we conclude that whenever J(f) belongs to a smooth

TRANSCENDENTAL MEROMORPHIC SOLUTIONS OF SOME ALGEBRAIC DIFFERENTIAL EQUATIONS

open access: yes, 2007
In this paper we treat transcendental meromorphic solutions of some algebraic differential equations. We consider the number of distinct transcendental meromorphic solutions. Algebraic relations between meromorphic solutions and comparisons of the growth

On the Complex Oscillation of Meromorphic Solutions of Nonhomogeneous Linear Differential Equations with Meromorphic Coefficients

open access: yesDiscrete Dynamics in Nature and Society, 2020
In this paper, we study the higher order differential equation fk+Bf=H, where B is a rational function, having a pole at ∞ of order n>0, and H≡0 is a meromorphic function with finite order, and obtain some properties related to the order and zeros of its

The star function for meromorphic functions of several complex variables [PDF]

open access: yes, 2019
We define an analogue of the Baernstein star function for a meromorphic function f in several complex variables. This function is subharmonic on the upper half-plane and encodes some of the main functionals attached to f. We then characterize meromorphic

An Inequality of Meromorphic Functions and Its Application

open access: yesThe Scientific World Journal, 2014
By applying Ahlfors theory of covering surface, we establish a fundamental inequality of meromorphic function dealing with multiple values in an angular domain.

Orbit Growth of Shift Spaces Induced by Bouquet Graphs and Dyck Shifts

open access: yesMathematics, 2021
For a discrete dynamical system, the prime orbit and Mertens’ orbit counting functions describe the growth of its closed orbits in a certain way. The asymptotic behaviours of these counting functions can be determined via Artin–Mazur zeta function of the

On $L^*$-proximate order of meromorphic function [PDF]

open access: yes, 2018
In this paper we introduce the notion of $L^{* }$-proximate order of meromorphic function and prove its ...

Properties of Meromorphic Spiral-Like Functions Associated with Symmetric Functions

open access: yesJournal of Function Spaces, 2022
To consolidate or adapt to many studies on meromorphic functions, we define a new subclass of meromorphic functions of complex order involving a differential operator.

Value Distribution and Uniqueness Results of Zero-Order Meromorphic Functions to Their q-Shift

open access: yesDiscrete Dynamics in Nature and Society, 2012
We investigate value distribution and uniqueness problems of meromorphic functions with their q-shift. We obtain that if f is a transcendental meromorphic (or entire) function of zero order, and Q(z) is a polynomial, then afn(qz)+f(z)−Q(z) has infinitely
