Subordination and superordination results for the family of Jung-Kim-Srivastava integral operators

Abstract

In this paper, we derive some subordination and superordination results associated with the family of Jung-Kim-Srivastava integral operators defined on the space of meromorphic functions. Several sandwich-type results are also obtained.

Differential subordination and superordination results for certain subclasses of analytic functions by the technique of admissible functions

“…In an earlier investigation, a sequence of results using differential subordination with convolution for the univalent case has been studied by Shanmugam [19] while sharp coefficient estimates for a certain general class of spirallike functions by means of differential subordination was studied by Xu et al [25]. A systematic study of the subordination and superordination using certain operators under the univalent case has also been studied by Shanmugam et al [20][21][22][23] and by sun et al [24]. We observe that for these results, many of the investigations have not yet been studied by using appropriate classes of admissible functions.…”
