On unavoidable families of meromorphic functions

open access: yes, 2023
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 $\C$.

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 a Certain Subclass of Meromorphic Functions Defined by a New Linear Differential Operator

open access: yesJournal of Mathematical and Fundamental Sciences, 2017
In this article, a new linear differential operator I^k (L_s^a (a_l,b_m )f(z)) is defined by using the Hadamard product of the q-hypergeometric function and a function related to the Hurwitz-Lerch zeta function. By using this linear differential operator,

A note on power of meromorphic function and its shift operator of certain hyper-order sharing one small function and a value

open access: yesМатематичні Студії, 2021
In this article, we obtain two results on $n$ the power of a meromorphic function and its shift operator sharing a small function together with a value which improve and complement some earlier results.

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.

Examining the Function of Meromorphic with Using the Linear Convolution Operator [PDF]

open access: yes, 2021
In this study, it is mentioned that meromorphic functions are univalent functions that are analytical everywhere. Complex analytical transformations were investigated by mentioning the necessary form for( )f z to have meromorphic function.
