关于Liu-Owa积分算子的双重从属保持性质

摘要

本文研究了单位圆盘内关于Liu-Owa积分算子的多叶解析函数类的从属和超从属保持问题。利用微分从属的方法，获得了该类函数的中间型结果，推广和改进了一些已知结果。%In the paper, we investigate subordination and superordination preserving prob-lems for analytic and multivalent functions in the open unit disk, which are associated with the Liu-Owa integral operator. By using the method of differential subordination, we derive sandwich-type results of functions belonging to these classes, which generalize and improve some previous known results.
