Archivum Mathematicum

The present investigation deals with a new subclass of alpha-convex bi-univalent functions in the unit disc E = z : z < 1 defined with q -derivative operator. Bounds for the first two coefficients and Fekete-Szegö inequality are established for this class. Many known results follow as consequences of the results derived here.
