TY - JOUR ID - TI - IJ-w-Perfect Functions Between Bitopological Spaces الدوال التامة من النمط-IJ-w بين الفضاءات التبولوجية الثنائية AU - Y. Y. Yousif يوسف يعكوب يوسف AU - N. S. Jassim نيران صباح جاسم PY - 2010 VL - 23 IS - 2 SP - 135 EP - 140 JO - Ibn Al-Haitham Journal For Pure and Applied Sciences مجلة ابن الهيثم للعلوم الصرفة والتطبيقية SN - 16094042 25213407 AB - In this paper we introduce a lot of concepts in bitopological spaces which are ij-ω-converges to a subset, ij-ω-directed toward a set, ij-w-closed functions, ij-w-rigid set, ij-w-continuous functions and the main concept in this paper is ij--perfect functions between bitopological spaces. Several theorems and characterizations concerning these concepts are studied.
