Özet
In this work, we employ the Salagean q-differential operator in conjunction with involution numbers to define a new subclass of bi-univalent functions ithe open unit disk. For this class, we derive coefficient estimates, including boundfor the general Taylor–Maclaurin coefficients and the Fekete–Szegő functional co-efficients.
