摘要
A(n)表示在z<1内的解析函数f(z)=z-k∑=∞n+1akzk(an≥0,n∈N=,1,2,3,…,)组成的类。通过引进A(n)的新子类S*(n,α,λ)和K(n,α,λ),研究了S*(n,α,λ)和K(n,α,λ)的系数估计,偏差定理及其极值点。
Let A(n) denote the class of functions of the form f(z)=z-k∑=∞n+1akzk(an≥0,n ∈N=,1,2,3,…,,which is analyzed in z <1.This paper introduces a subclass S*(n,α,λ) and K(n,α,λ).Its coefficient estimates,distortion theorem and extreme point are studied.
