一类负系数星像函数类

A Subclass of Certain Starlike Functions with Negative Coefficients

在A(n)上引入了Salagean算子,讨论了由该算子定义的A(n)中具有负系数函数类Tn(m,λ,μ,α)的性质,得到关于该函数类的系数估计,偏差定理等,这些结果都是精确的,并推广了一些已知结果。

Using the salagean operator, introduce the subclass Tn （ m, λ ,μ, α） with negative coefficients, some results such as coefficients estimates, distortion theorems for this class are given here, which extends some known results.
