Romaguera Bonilla, Salvador2023-07-272023-07-272022-08-11https://riunet.upv.es/handle/10251/195662[EN] We characterize the completeness of fuzzy quasi-metric spaces by means of a fixed point theorem of Kannan-type. Thus, we extend the classical characterization of metric completeness due to Subrahmanyam as well as recent results in the literature on the characterization of quasi-metric completeness and fuzzy metric completeness, respectively. We also introduce and discuss contractions of Chatterjea-type in this asymmetric context.Reserva de todos los derechosFuzzy quasi-metric spaceQuasi-metric spaceCompleteFixed pointKannan contractionChatterjea contractionContractions of Kannan-type and of Chatterjea-type on fuzzy quasi-metric spacesArtÃculo10.53006/rna.1140743Abierto2636-7556
