Value distribution of difference polynomials of meromorphic functions

Abstract

In this article, we study the value distribution of difference polynomials of meromorphic functions, and obtain some results which can be viewed as discrete analogues of the results given by Yi and Yang [11]. We also consider the value distribution of $$ \phi(z)=f(z)(f(z)-1)\prod_{j=1}^{n}f(z+c_j). $$
