| Abstract: |
| This paper establishs difference analogues of some classical results about Hayman problem by the Nevanlinna theory，we have obtained the precise estimation of the lower bound of the zero - density of a class of difference polynomials and improved some previously results. |
| Key words: Difference polynomials Value distribution Zero |
