Recently, q-analogue of Noor integral operator and other special operators became importance in the field Geometric Function Theory. In this study, by connecting principle subordination we introduced an interesting class bi-univalent functions obtained coefficient estimates for new class.

Recently, many papers in the theory of univalent functions have been devoted to mapping and characterization properties of various linear integral or integro-differential operators in the class S (of normalized analytic and univalent functions in the open unit disk U), and in its subclasses (as the classes S∗ of the starlike functions and K of the convex functions in U). Among these operators, ...

People who spend time together begin to experience the world in similar ways, coming in fact to share the world. Just a few days ago, my wife and I walked through downtown Victoria to pick up a stereo amplifier from the repair shop when I noticed her head move slightly left to right. I turned my head in the direction of her gaze, and, before we began talking, I knew she was alerting me to the a...

Article history: Received 23 April 2013 Accepted after revision 21 May 2013 Available online 30 May 2013 Presented by the Editorial Board Applying the Faber polynomial coefficient expansions to a class of meromorphic biunivalent functions, we obtain the general coefficient estimates for such functions and also examine their early coefficient bounds. A function univalent in the open unit disk is...
