Abstract AR
درس Chae و آخرون سنة 1995 مفهومين -strongly -continuous function و closed graph- (, ) الهدف من هذا البحث هو دراسة مجموعة من المميزات و الخواص للمفهومين.
و كذلك تعريف نوع جديد من الدالة المفتوحة من النمط -، و تكون هذه الدالة أقوى من الدالة من النمط quasi -open و من ثم أقوى من strongly -open، و هكذا حصلنا على مجموعة من الميزات و الخواص لهذه الدالة.
و هذا يوضح أن الرسم البياني لدالة f هو closed graph- (, ) إذا و فقط إذا كان لكل fiter base في فضاء X متقاربة من النمط إلى بعض نقاط p في X بحيث أن () f متقاربة من النمط إلى بعض نقاط q في Y يحقق q = (p) f.
Abstract EN
Chae et.
al.
(1995) have studied the concept of a-strongly q-continuous functions and (a, q)-closed graph.
The aim of this paper is to investigate several new characterizations and properties of a-strongly q-continuous functions and (a, q)-closed graph.
Also, we define a new type of functions called aq-open functions, which is stronger than quasi a-open and hence strongly a-open, and we obtain some characterizations and properties for it.
It is shown that the graph of f, G (f) is (a, q)-closed graph if and only if for each filter base Y in X q-converging to some p in X such that f (Y) a-converges to some q in Y holds, f (p) = q.
