A fixed point theorem for preordered complete fuzzy quasi-metric spaces and an application

Castro Company, Francisco; Romaguera Bonilla, Salvador; Tirado Peláez, Pedro (SpringerOpen, 2014-03)

We obtain a fixed point theorem for a type of generalized contractions on preordered complete fuzzy quasi-metric spaces which is applied to deduce, among other results, a procedure to show in a direct and easy fashion the ...
Fuzzy Quasi-Metric Spaces: Bicompletion, Contractions on Product Spaces, and Applications to Access Predictions

Castro Company, Francisco (Universitat Politècnica de València, 2010-07-05)

Desde que L.A. Zadeh presentó la teoría de conjuntos difusos en 1965, esta se ha usado en una amplia serie de áreas de las matemáticas y se ha aplicado en una gran variedad de escenarios de la vida real. Estos escenarios ...
On the bicompletion of intuitionistic fuzzy quasi-metric spaces

Castro Company, Francisco; Tirado Peláez, Pedro (2016)

[EN] Based on previous results that study the completion of fuzzy metric spaces, we show that every intuitionistic fuzzy quasi-metric space, using the notion of fuzzy metric space in the sense of Kramosil and Michalek to ...
On the construction of metrics from fuzzy metrics and its application to the fixed point theory of multivalued mappings

Castro Company, Francisco; Romaguera Bonilla, Salvador; Tirado Peláez, Pedro (SPRINGER INTERNATIONAL PUBLISHING AG, 2015)

[EN] We present a procedure to construct a compatible metric from a given fuzzy metric space. We use this approach to obtain a characterization of a large class of complete fuzzy metric spaces by means of a fuzzy version ...
On Yager and Hamacher t-Norms and Fuzzy Metric Spaces

Castro Company, Francisco; Tirado Peláez, Pedro (Wiley: 12 months, 2014-12)

Recently, Gregori et al. have discussed (Fuzzy Sets Syst 2011;161:2193 2205) the so-called strong fuzzy metrics when looking for a class of completable fuzzy metric spaces in the sense of George and Veeramani and state the ...
The bicompletion of fuzzy quasi-metric spaces

Castro Company, Francisco; Romaguera Bonilla, Salvador; Tirado Peláez, Pedro (Elsevier, 2011-03-16)

Extending the well-known result that every fuzzy metric space, in the sense of Kramosil and Michalek, has a completion which is unique up to isometry, we show that every KM-fuzzy quasi-metric space has a bicompletion which ...
