يقدم هذا البحث طريقة معينة لتحديد مجموعات تحول قيم بعض الداليات الخطية في فضاء كاراتيودوري المعمم و هو فضاء التوابع التحليلية في قرص الواحدة التي تقبل التمثيل التكاملي الآتي:
حيث دالة غير متناقصة ضمن المجال و تحقق الشرط . و قد تم ، في هذا الفضاء، البرهان على أن مجموعة قيم الدالي:
عندما تكون كثيرة حدود في القرص ، هي قرص مغلق تم تحديد مركزه و نصف قطره . و قد تم أيضاً تحديد مستقرات بعض الداليات الأخرى في هذا الفضاء.
This paper presents a certain method to determine the range of variability of some functionals defined in Generalized Caratheodory Class ( i.e the class of analytic functions in the unit disk of the form:
where is a non decreasing function on the interval such that ). It has been proved that the range of variability of functional
where is a polynomial in , is the closed disc with and precisely determined . Also the range of variability of some other functional determined

In this research, we have studied the issue of approximation of complex functions from weighted Lebesgue space ; and (Mukenhoupt weight) to rational functions by using p- Faber polynomials on large group of curves, which called Carlson curves. This
We study in this research approximation of complex functions from Orlicz space on a subclass of Carlson curves, which called Dini smooth curves to rational functions by using polynomials related with Dzjadyk sums which obtained from Faber polynomials. We depend on some concepts of complex analysis such as formulas of Sokhotski to reach the desired goal
Prior research has explored the ability of computational models to predict a word semantic fit with a given predicate. While much work has been devoted to modeling the typicality relation between verbs and arguments in isolation, in this paper we tak
