Abstract (2. Language): 
In this paper, we introduce and investigate an interesting subclass Bh;p (A) of analytic and bi-univalent functions in the open unit disk U. For functions belonging to the class Bh;p (A), obtain estimates on the Frst two coefcients ja2j and ja3j. The results presented in this paper generalize and improve some recent works of Frasin et al. [B.A.Frasin, M.K.Aouf, New subclasses of bi-univalent functions, Appl. Math. Lett. 24:1569-1573, 2011] and Srivastava et al. [Qing-Hua Xu, Ying-Chun Gui, H.M.Srivastava, coefcient estimates for a certain subclass of analytic and bi-univalent functions, Appl. Math. Lett. 25: 990-994, 2012].
