    • On some constructions of new triangular norms 

      Mesiar, Radko (Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 1995)
      Article
      Open Access
      We discuss the properties of two types of construction of a new t-norm from a given t-norm proposed recently by B. Demant, namely the dilatation and the contraction. In general, the dilatation of a t-norm is an ordinal sum ...
    • On some geomtric transformation of t-norms 

      Klement, E. P. (Erich Peter); Mesiar, Radko; Pap, Endre (Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 1998)
      Article
      Open Access
      Given a triangular norm $T$, its $t$-reverse $T^*$, introduced by C. Kimberling ({\it Publ. Math. Debrecen} 20, 21-39, 1973) under the name invert, is studied. The question under which conditions we have $ T^{**} = T$ is ...
    • Weighted sums of aggregation operators 

      Calvo Sánchez, Tomasa; Baets, Bernard de; Mesiar, Radko (Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 1999)
      Article
      Open Access
      he aim of this work is to investigate when a weighted sum, or in other words, a linear combination, of two or more aggregation operators leads to a new aggregation operator. For weights belonging to the real unit interval, ...
