SalehDepartment of Mathematics, Faculty of Science, Assiut University, Assiut, EgyptJournal Article20130730The aim of this paper is to prove some common fixed point theorems for fourĀ mappings satisfying $(psi,varphi)$-weak contractions involving rational expressions in ordered partial metric spaces. Our results extend, generalize and improve some well-known results in the literature. Also, we give two examples to illustrate our results.http://ijnaa.semnan.ac.ir/article_468_a5b9c5cc09ff9b3a978f98266a1b155a.pdf
