Romaguera Bonilla, Salvador2023-06-202023-06-202022-12-30https://riunet.upv.es/handle/10251/194430[EN] In this note we show the somewhat surprising fact that the proof of the `if part' of the distinguished characterizations of metric completeness due to Kirk, and Suzuki and Takahashi, respectively, can be deduced in a straightforward manner from Hu's theorem that a metric space is complete if and only if any Banach contraction on bounded and closed subsets thereof has a fixed point. We also take advantage of this approach to easily deduce a characterization of metric completeness via fixed point theorems for α − ψ-contractive mappings.Reconocimiento (by)Fixed pointComplete metric spaceArtículo10.31197/atnaa.1090077Abierto2587-2648
