通过研究f(qz+c)/f(z)的均值函数,得到Nevanlinna理论第二基本定理的q阶差分对应.作为应用,给出了T(r,f(qz+c))与T(r,f)之间的关系,并考虑了函数f(z)与f(qz+c)的分担值问题.
In this paper,we investigate the proximity function of f(qz+c)/f(c) and present a q-shift difference analogue of the second main theorem of Nevanlinna theory.As applications,we will give the relation of T(r,f(qz + c)) and T(r,f),and consider the value sharing problem of f(z) and its q-shift difference f(qz + c) as well.
