  • Aggregation operators and lipschitzian conditions 

    Recasens Ferrés, Jorge (Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 2008)
    Article
    Accés obert
    Lipschitzian aggregation operators with respect to the natural T - indistin- guishability operator Et and their powers, and with respect to the residuation ! T with respect to a t-norm T and its powers are studied. A ...

  • Representing upper probability Measures over rational Lukasiewicz logic 

    Marchioni, Enrico (Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 2008)
    Article
    Accés obert
    Upper probability measures are measures of uncertainty that generalize probability measures in order to deal with non-measurable events. Following an approach that goes back to previous works by H ajek, Esteva, and ...

  • Exploring a syntactic notion of modal many-valued logics 

    Bou, F.; Esteva, F.; Godo, L. (Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 2008)
    Article
    Accés obert
    We propose a general semantic notion of modal many-valued logic. Then, we explore the di culties to characterize this notion in a syntactic way and analyze the existing literature with respect to this framework

  • On the threshold of bounded pseudo-distances 

    Trillas, Enric; Soto, Adolfo R. de (Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 2008)
    Article
    Accés obert
    This paper deals with the relationship between bounded pseudo-distances and its associated W'-indistinguishabilities, from which the idea of threshold of transitivity comes. By the way, bounded pseudo-distances are characterized

  • Orderings of fuzzy sets based on fuzzy orderings. Part I: the basic approach 

    Bodenhofer, Ulrich (Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 2008)
    Article
    Accés obert
    The aim of this paper is to present a general framework for comparing fuzzy sets with respect to a general class of fuzzy orderings. This approach includes known techniques based on generalizing the crisp linear ordering ...
