Özet

In this paper we introduce and investigate an interesting subclass LB(graphic)(lambda) of analytic and bi-univalent functions in the open unit disk U. For functions belonging to the class LB(graphic)(lambda), we obtain estimates on the first two Taylor-Maclaurin coefficients a(2) and a(3). The results presented in this paper would generalize and improve some recent work of JJoshi et al. 5 ].
