A normality criterion for meromorphic functions having multiple zeros

Shanpeng Zeng, Indrajit Lahiri (2014)

Annales Polonici Mathematici

Similarity:

We prove a normality criterion for a family of meromorphic functions having multiple zeros which involves sharing of a non-zero value by the product of functions and their linear differential polynomials.

In the paper we prove a uniqueness theorem for meromorphic functions which provides an answer to a question of H. X. Yi.

Meromorphic functions that share a nonzero polynomial IM

Pulak Sahoo (2012)

Mathematica Bohemica

Similarity:

We study the uniqueness theorems of meromorphic functions concerning differential polynomials sharing a nonzero polynomial IM, and obtain two theorems which will supplement two recent results due to X. M. Li and L. Gao.

On uniqueness for nonlinear differential polynomials sharing the same 1-point

Abhijit Banerjee (2006)

Annales Polonici Mathematici

Similarity:

We study the uniqueness of meromorphic functions when two nonlinear differential polynomials generated by two meromorphic functions share the same 1-points. Our results improve results of Fang-Fang and Lin-Yi and supplement a recent result of Lahiri-Pal.
