Cone metric spaces and fixed point theorems of contractive mappings. (English) Zbl 1118.54022

The authors introduce the notion of a cone metric space \((X,d)\). In the classical definition of a metric space they replace the set of real numbers by a Banach space \(E\) ordered by a solid cone \(P\). They discuss properties of cone metric spaces and prove some fixed point theorems for mappings satisfying contractive conditions with respect to a cone metric \(d\).
