摘要
讨论 Schwarz函数的系数不等式 ,证明了当 f(z) = ∞n=0anzn 从属于 g(z) = ∞n=0bnzn时 ,| a3|≤ 2 max{ | b1 ,| b2 | ,| b3| } ,并且等号是可达的 .
A coefficient inequality of Schwarz function is proved in this paper,and the following resulf is obtained:if f(z)=∞n=0a nz n is subordinate to g(z)=∞n=0b nz n, then |a 3|≤2 max {|b 1|,|b 2|,|b 3|},and the bownd is sharp.
