On unavoidable families of meromorphic functions

, 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 $\C$.

Some inequalities on meromorphic function and its derivative concerning small functions in an angular domain

Journal of Inequalities and Applications, 2016
In this paper, we investigate the value distribution of a meromorphic function and its derivative concerning small functions in an angular domain and obtain some inequalities for a meromorphic function in an angular domain, which improve the previous ...

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

Journal 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,
