| Abstract: |
| In this paper, we study difference analogues of some classical results about Hayman problem. By the Nevanlinna theory, we obtain the precise estimation of the lower bound of the zero counting function of a class of difference polynomials and improve some previously results. |
| Key words: difference polynomials value distribution zero |
