A fuzzy set on a finite universe can be interpreted as a vector in a unit cube. This gives rise to a huge variety of approaches in order to aggregate finite fuzzy sets or to modify a given one. We analyze several geometrical ... -
On fixed point theory in partially ordered sets and an application to asymptotic complexity of algorithms
Estevan Muguerza, Asier ; Miñana, Juan José; Valero, Óscar (Springer, 2019)
Artículo / Artikulua
The celebrated Kleene fixed point theorem is crucial in the mathematical modelling of recursive specifications in Denotational Semantics. In this paper we discuss whether the hypothesis of the aforementioned result can be ... -
Quasi-metrics for possibility results: intergenerational preferences and continuity
Estevan Muguerza, Asier ; Maura, Roberto; Valero, Óscar (MDPI, 2023)
Artículo / Artikulua
In this paper, we provide the counterparts of a few celebrated impossibility theorems for continuous social intergenerational preferences according to P. Diamond, L.G. Svensson and T. Sakai. In particular, we give a topology ...
