Some Notes on the paper 'The Equivalence of Cone Metric Spaces and Metric Spaces'

摘要

In this paper we shall show that the metrics are equivalent which obtained byFeng and Mao in [[1], Y. Feng and W. Mao, Equivalence of Cone Metric spaces andMetric Spaces, Fixed Point Theory, 11(2)(2010), 259-264.] and Du in [[2],Wei-Shih Du, A Note on Cone Metric Fixed Point Theory and its equivalence,Nonlinear Analysis, 72 2259-2261 (2010)]. Also in the sequel we calculate someexamples by one of the metrics.
