Normality concerning two families of meromorphic functions

Banarsi Lal, Virender Singh

University of Jammu; University of Jammu

Abstract

In this paper, we study normality concerning two families of meromorphic functions. In particular, we investigate the sharing conditions under which normality of one family implies the normality of other. Results obtained in this paper extend some earlier works of several authors.

Keywords: Normal families, meromorphic function, differential polynomials, Nevanlinna theory
