A Note on '<i>n</i>-fixed Point Theorems for Nonlinear Contractions in Partially Ordered Metric Spaces'

Abstract

In this note we prove that a kind of mappings depending on k arguments introduced in (Paknazar et al. in Fixed Point Theory Appl. 2013: 111, 2013) only depend on their first argument. Therefore, results in that paper reduce to the unidimensional case. We also include some commentaries about the different notions of multidimensional fixed point.
