Özet
The partial sums f3(z) of some extermal functions for various classes S∗, K
and R of starlike functions, convex functions and functions with positive real
part in the open unit disk U, respectively, are discussed. In general, the partial
sums can not preserve the same character as the initial functions. The object
of the present paper is to discuss the radius problems for partial sums of some
extremal functions for the classes S∗, K and R.
