Abstract :In this paper, we introduce a new subclass $\mathcal{LB}_{\Sigma }^{\lambda }\leftinsert ignore into journalissuearticles values( \varphi \right); $ of analytic and bi-univalent functions in the open unit disk $\mathbb{U}.$ For functions belonging to this class, we obtain initial coefficient bounds.\ Our results generalize and improve some earlier results in the literature
Keywords : Analytic functions, univalent functions, bi univalent functions, coefficient bounds, subordination, pseudo starlike functions
