Majorization problem for two subclasses of meromorphic functions associated with a convolution operator

open access: yes, 2020
In the present paper, we investigate a majorization problem for the class $% M_{\alpha ,\beta }^{\nu ,j}(\eta ,\varkappa ;A,B)$ of meromorphic functions and the class $N_{\alpha ,\beta }^{\nu ,j}(\theta,b;A,B)$ of meromorphic spirllike functions related ...

Fatou components and singularities of meromorphic functions [PDF]

open access: yesProceedings of the Royal Society of Edinburgh. Section A Mathematics, 2017
We prove several results concerning the relative position of points in the postsingular set P(f) of a meromorphic map f and the boundary of a Baker domain or the successive iterates of a wandering component.

Fekete–Szegö Problems for Certain Classes of Meromorphic Functions Involving q-Al-Oboudi Differential Operator

open access: yesJournal of Mathematics, 2022
In this paper, we introduce a new derivative operator involving q-Al-Oboudi differential operator for meromorphic functions. By using this new operator, we define a new subclass of meromorphic functions and obtain the Fekete–Szegő inequalities.

On Meromorphic Functions Defined by a New Operator Containing the Mittag-Leffler Function

open access: yesSymmetry, 2019
This study defines a new linear differential operator via the Hadamard product between a q-hypergeometric function and Mittag–Leffler function. The application of the linear differential operator generates a new subclass of meromorphic function ...

On the uniqueness of meromorphic functions that share three sets [PDF]

open access: yes, 2009
summary:With the aid of the notion of weighted sharing and pseudo sharing of sets we prove three uniqueness results on meromorphic functions sharing three sets, all of which will improve a result of Lin-Yi in Complex Var. Theory Appl. (2003)
