![Estimates of First Two Coefficients of Analytic Functions of a Certain Class of Bi-Univalent Functions using OPPLA Differential Operator](https://icrrd.com/public/media/28-07-2022-055538oppela.jpg)
ABSTRACT: In this paper, we have used Opoola Differential Operator, a generalization of Sl
gean Differential Operator and Al-Oboudi Differential Operator to define a new subclass of analytic and bi-univalent functions using quasi-subordination principle. We have obtained upper estimates for the first two coefficients of functions in the this subclass by means of Ma-Minda functions.
