A Common Fixed Point Theorem of Weak Contraction Mappings on Partially Ordered Quasi Metric Space

摘要

The fixed point theorem on weak contraction mapping in partially ordered quasi metric space was presented in previous work. This theorem has provided generalization results from fixed point on weakly contractive that uses altering distance function. In this paper, we prove a common fixed point of contraction mapping on partially ordered quasi metric space. As a comparison, we also present the shorter proof of this theorem.
