利用Nevan linna代数体函数的值分布理论,进一步讨论了1959年Haym an提出的函数f′fn的值分布问题,推广了Katajam ak i有关单项式值分布的结论,得到了一个更为理想的结果.
Using Nevanlinna theory of value distribution for algebroid functions,the value distribution problem of the function f′f~n noted by Hayman in 1959 is discussed.A value distribution result for differential nomials due to Katajamaki is generalized.
