Some Notes on the paper "The Equivalence of Cone Metric Spaces and Metric Spaces"
arXiv:1103.2558
Abstract
In this paper we shall show that the metrics are equivalent which obtained by Feng and Mao in [[1], Y. Feng and W. Mao, Equivalence of Cone Metric spaces and Metric 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 some examples by one of the metrics.
