Abstract
"Radius constants for functions in three classes of analytic functions to be a starlike function of order α, parabolic starlike function, starlike function associated with lemniscate of Bernoulli, exponential function, cardioid, sine function, lune, a particular rational function, and reverse lemniscate are obtained. One of these classes are characterized by the condition Re g/(zez ) > 0. The other two classes are defined by using the function g and they consist respectively of functions f satisfying Re f/g > 0 and |f/g − 1| < 1. Keywords: Starlike function, radius of starlikeness, exponential function."
