On λ-pseudo bi-starlike and λ-pseudo bi-convex functions with respect to symmetrical points

S. S. Eker, B. Seker

In this paper, defining new interesting classes, λ-pseudo bi-starlike functions with respect to symmetrical points and λ-pseudo bi-convex functions with respect to symmetrical points in the open unit disk U, we obtain upper bounds for the initial coefficients of functions belonging to these new classes.
