تحديد مجموعات قيم بعض الداليات في فضاءات الدوال الممثلة بالتكامل

This paper presents a certain method of determining the range of variability of some linear functional defined by the Caratheodory Class (i.e. the class of analytic functions in the unit disk with a real positive part f(0)=1) and by the Class of Starlike Functions related to it. Using the integral representation of functions in these classes, some estimations for the functional of the type have been obtained.
