Abstract: |
In this paper we introduce and study some properties of a unified class ![$ mathcal{U [mu,alpha,beta,gamma,lambda,eta,A,B]$](images/083_05_JIPAM/img1.gif) of prestarlike functions with negative coefficients in a unit disk  . These properties include growth and distortion, radii of convexity, radii of starlikeness and radii of close-to-convexity.
