【摘要】 对于一类由Salagean微分算子定义的复数阶解析函数,给出其充分条件。利用数学归纳法及正实部函数族Herglotz定理的推论,给出该类函数的系数估计不等式,研究并得到当参数取任意复数时其Fekete-Szeg不等式。更多还原

【Abstract】 A class of analytic functions defined by Salagean differential operator of complex order is introduced,and its sufficient condition is given.The inequality of coefficient and the Fekete-Szeg inequality of the new class are provided,by using mathematical induction and a deduction of Herglotz theorem.更多还原
