    Abstract :

    This Study Presents A New Convolution Operator Constructed Through The Hadamard Product Of The Komatu Integral Operator With The Opoola Differential Operator. By Applying Quasi-subordination, Two New Subclasses Of Bi-univalent Functions Are Defined In The Open Unit Disk 𝑈. For These Subclasses, Estimates Are Obtained For The Coefficients |𝒹𝟸 | And |𝒹3 |. In Addition, The Fekete-Szegӧ Inequalities Are Established For The Introduced Subclasses. Several Known Results Are Recovered As Special Cases By Suitable Choices Of The Involved Parameters.
