On inequalities for certain analytic functions. (English) Zbl 0723.30009
Author’s abatract: The purpose of the present paper is to show some properties of functions $$F_{\lambda}(z)=(1-\lambda)f(z)+\lambda zf'(z)$$ ($$\lambda\in {\mathbb{C}})$$ defined by using an analytic function f(z) in the unit disk.
