摘要
设A是单位圆盘U={z:z<1,z∈C}内的单叶解析函数族.给出A的子族.DM g(α,β)={f(z)∈A:Re{z(f*g)'(z)/(f*g)(z)}<β|z(f*g)'(z)/(f*g)(z)-1|+α,g(z)∈A},这里α>1,β≤0,介绍了一类积分算子函数I n(z)及其特殊类型的积分算子函数Ik n(z),G n(z),F n(z),利用解不等式的技巧和解析函数理论,研究得到了一些它们的性质,推广了一些已有的结论.
A is denoted the class of functions which is univalent and analytic in the open unit disc U={z:〖JB(|〗z〖JB)|〗1,β≤0 is introduced. One integral operator In(z) and its special types Ikn(z), Gn(z), Fn(z) are also introduced. Some properties involving these operators are determined by using solutions of inequalities techniques and theories of analytic functions. The sharp results generalize some known results.
