A normality criterion generalizing Gu's result

TL;DR

This paper establishes a new normality criterion for families of meromorphic functions that involves sharing functions, extending previous results including Gu's criterion.

Contribution

It introduces a generalized normality criterion for meromorphic functions that broadens the scope of earlier theorems, including Gu's result.

Findings

Generalizes Gu's normality criterion

Involves sharing of functions in the criterion

Extends applicability to broader classes of meromorphic functions

Abstract

In this paper we prove a normality criterion for the families of meromorphic functions involving sharing of functions. Our result generalizes some of the earlier results on Gu's normality criterion.
