本文考虑零级亚纯函数的q-移位差分多项式的零点分布，得到了两个定理，将经典的Hayman结果推广到q-移位差分多项式的零点。我们还研究了具有公共值的q移位差分多项式的唯一性问题。
In this paper, we consider the zero distributions ofq-shift difference polynomials of meromorphic functions with zero order, and obtain two theorems that extend the classical Hayman results on the zeros of differential polynomials toq-shift difference polynomials. We also investigate the uniqueness problem ofq-shift difference polynomials that share a common value.
