Owa, Shigeyoshi Some properties of certain analytic functions. (English) Zbl 0646.30017 Soochow J. Math. 13, No. 2, 197-201 (1987). Summary: The object of the present paper is to show some interesting properties of certain analytic functions F(z) defined by \[ F(z)=(1- \lambda)f(z)+\lambda zf'(z)\quad (\lambda \geq 0) \] for f(z) which is analytic in the unit disk.
