Replacing the set of real numbers by an ordered Banach space in the definition of a metric, Guang and Xian (5) introduced the concept of a cone metric and obtained some fixed point Theorems for contractive mappings on cone metric spaces. It has been shown that every cone metric space is metrizable (2-4). In this paper we review and simplify some results of (6) and as a consequence of our earlier results and in a totally different way will show again that every cone metric space is metrizable… Expand

Let (E, τ) be a topological vector space and P a cone in E. We shall define a topology τP on E so that (E, τP) is a normable topological vector space and P is a normal cone with normal constant M =… Expand

We present some fixed point results for monotone operators in a metric space endowed with a partial order using a weak generalized contraction-type assumption.
