Abstract

The aim of this paper is to give the radius of starlikeness of the certain classes of -valent functions defined by multiplier transformations. The results are obtained by using techniques of Robertson (1953,1963) which was used by Bernardi (1970), Libera (1971), Livingstone (1966), and Goel (1972).
