Let f(x) = z+ sum (for n=k+1 to infinity) belong to the class S(1 - b),beta), b=0,, complex and 0 < beta < 1. In this paper, we determine sharp coefficient estimates for functions of the form f(z)t = zt + sum (for n=t+kan zn to infinity), where t is a positive integer. The results obtained generalize the work of many authors.
