Abstract
LOZADA-CRUZ, GERMAN. A Simple Observation Concerning Contraction Mappings. Rev.colomb.mat. [online]. 2012, vol.46, n.2, pp.229-233. ISSN 0034-7426.
In this short note we show that the results obtained by Walter in [4] remain valid if we change the metric σ by another metric. Furthermore, if we use the norm |\cdotbold|T,\epsilon given in [3], Theorem B in[4] remains valid.
Keywords : Contraction; contraction principle; fixed point.
