The analytic description of holomorphic mappings is coupled with the functions which map the unit disk to the right half plane. Also, a natural extension of the idea of inequalities between real-valued functions is the concept of subordination between functions of a complex variable. In this study, we make use of some first-order differential subordination and superordination conditions on functions associated with 2j,k-symmetrical points, and determine some already known classes of analytic functions. We're also come up with some sandwich theorems based on specific assumptions about the parameters that are involved in our major findings.
