Abstract

This paper presents a new general subfamily (Formula presented.) of the family (Formula presented.) that contains holomorphic normalized m-fold symmetric bi-univalent functions in the open unit disk (Formula presented.) associated with the Ruscheweyh derivative operator. For functions belonging to the family introduced here, we find estimates of the Taylor–Maclaurin coefficients (Formula presented.) and (Formula presented.), and the consequences of the results are discussed. The current findings both extend and enhance certain recent studies in this field, and in specific scenarios, they also establish several connections with known results.
