Abstract

In the present paper we aim at proving some subordinations properties for meromorphic
functions analytic in the punctured unit disc  = {z : 0 < |z| < 1} with a simple
pole at the origin. The functions under investigation are associated with two integral
operators Pγ
σ and Qγ
σ (see Lashin in Comput Math Appl 59:524–531, 2010, https:// doi.
org/ 10. 1016/j. camwa. 2009. 06. 015). Several other results and numerical examples are
also obtained.
