Value distribution of certain differential polynomials leading to some normality criteria
Kuldeep Singh Charak, Nikhil Bharti
In this paper, we prove some normality criteria concerning transitivity of normality from one family of meromorphic functions to another which improve and generalize some recent re…
Uniqueness of differential polynomials sharing one value
Kuldeep Singh Charak, Banarsi Lal
We prove some uniqueness results which improve and generalize results of Jiang-Tao Li and Ping Li[Uniqueness of entire functions concerning differential polynomials. Commun. Korean…
A Value Distribution Result and Some Normality Criteria using Partial Sharing of Small Functions
K. S. Charak, Shittal Sharma
In this paper, we first generalize a value distribution result of Lahiri and Dewan [4] and as an application of this result we prove a normality criterion using partial sharing of…
Uniqueness of Some Differential Polynomials of Meromorphic Functions
Kuldeep Singh Charak, Banarsi Lal
In this paper, we prove some uniqueness results which improve and generalize several earlier works. Also, we prove a value distribution result concerning which provides a…
Two normality criteria and counterexamples to the converse of the bloch's principle
Kuldeep Singh Charak, Virender Singh
In this paper, we prove two normality criteria for a family of meromorphic functions. The first criterion extends a result of Fang and Zalcman[Normal families and shared values of…
