摘要 研究一类超级σ2(f)<1的亚纯函数差分多项式的零点分布,改进了文献[1-2]的一些成果,也研究了分担小函数的超越整函数的唯一性问题. In this paper,we investigate the zeros distributions of certain difierence polynomials of meromorphic functions with hyper-orderσ2(f)<1,and improve some known results.We also investigate the uniqueness problem of difierence polynomials of transcendental entire functions.
