Abstract

Let A be the class of univalent functions f(z)=z+${\alpha}$$_2$z$^2$${\alpha}$$_3$z$^3$+…(1.1) which are analytic in the unit disk $\Delta$= {z:│z│<1}. Let S*(p) be the subclass of A composing of functions which are starlike of order $\rho$. A function f(z) belonging to the class A is said to be starlike of order $\rho$ ($\rho$(equation omitted) 0) if and only if z$\^$-l/ f(z) (equation omitted) 0 (z$\in$$\Delta$) and (equation omitted (1.2).(omitted)
