THE fekete-szego Inequality for Some Subclass of Analytic Functions related to In operator

摘要: 引入了一个与算子有关的解析函数类，利用函数的极值和单调性，讨论了此函数类的不等式.假设，为复数，则有 , ，且对所有的等号都成立. 当参数取一些特殊值时，得到一些特殊函数类的不等式.

Abstract: An analytical function class related to operator is introduced. By using the extremum of function and monotonicity, the sharp upper bounds of are discussed. If then and for all the following bound is sharp . When some special value for the parameters of and A and B, inequalities of some special function class are obtained.
