Bae studied the existence of fixed points for multivalued weakly contractive maps in the setting of metric and Banach spaces. We prove some results on the existence of coincidence points for multivalued f-weakly contractive nonself maps, which generalize and improve the corresponding results due to Bae, Latif and Tweddle and many others. Most recently, Feng and Liu generalized a multivalued version of the Banach contraction principle due to Nadler. We obtain coincidence points results for multivalued f-contractive selfmaps, which generalize the corresponding coincidence point result of Kaneko and the fixed point result of Feng and Liu. Moreover, in the setting of Banach spaces, we obtain a general coincidence point result for R-weakly commuting maps  Supervisor : Dr. AbdulLatif Noor Muhammad  Thesis Type : Master Thesis  Publishing Year : 1427 AH 2006 AD  Added Date : Wednesday, June 11, 2008  Researchers Researcher Name (Arabic) Researcher Name (English) Researcher Type Dr Grade Email عبدالله عقال المزروعي Al-Mazrui, Abdullah Egal Researcher Master   Files File Name Type Description  23713.pdf pdf Abstract  23714.pdf pdf المستخلص Back To Researches Page
