该文主要探讨了亚纯函数f(z)与其q阶差分算子△q,cf分担公共值的问题,是文献[15]研究内容的延续.例如,得到零级亚纯函数f(z)与△q,cf=f(qz+c)-f(z)分担四个公共值IM,则有f(z)=△q,cf成立.另外,当函数的级不为整数或无穷时,同样得到了f(z)与△q,cf的相关分担结果.
This research is a continuation of a recent paper [15]. Shared value problems related to a meromorphic function f(z) and its q-difference operator △q,cf are studied. It is shown, for instance, that if f(z) is of zero order and shares four values IM with its q-difference operator △q,cf = f(qz + c) - f(z), then f(z) = △q,cf . Moreover, we also consider problems on sharing values of f(z) and △q,cf when their orders are not an integer or infinite.
