Gheorghe Oros - On an integral operator and a starlike functions of order 1/2


Abstract: We consider the following integral operator:

It is well-known that if f is starlike, then
 F is also starlike. In this paper we will obtain some conditions
on f such that F be a starlike functions of order 1/2.
