Abstract

Many researchers have recently acquainted and researched several interesting subfamilies of bi-univalent function family 𝛿 and they have found non-sharp estimates on the first two Tay-lor-Maclaurin coefficients |𝑎2| and |𝑎3|. In this current work, the subfamily of bi-univalent functions in the sense of symmetric conjugate points with quasi subordination is defined. The Maclaurin coefficients |𝑎2|, |𝑎3| and besides related with these coefficients |𝑎3 − 𝑎22| for functions belonging to this subfamily are derived. Further some corollaries are also presented.
