    Migrativity of aggregation functions

  • Original language description

    In this paper we introduce a slight modification of the definition of migrativity for aggregation functions that allows useful characterization of this property. In this context we prove that there are no t-conorms, uninorms or nullnorms that satisfy migrativity and that the only migrative idempotent aggregation function is the geometric mean. The k-Lipschitz migrative aggregation functions are also characterized and the product is shown to be the only 1-Lipschitz migrative aggregation function. Finally, the associativity and bisymmetry of migrative aggregation functions are discussed.

    Migrativita agregačních funkcií

  • Czech description

    Pro agregační funkce jsme zavedli malou modifikci definice migrativity, která umožní vhodnou charakterizaci této vlastnosti. Ukázali jsme, že neexistují t-conormy, uninormy a nullnormy, které by vyhovovali migrativitě a že jediná migrativní idempotentníagregační funkce je geometrický příměr. Dále jsme charakterizovali k-Lipschitzovskou migrativní agregační funkci a ukázali jsme, že jediná 1-Lipschitzovská migrativní funkce je součin. Na závěr jsme se věnovali asociativitě a bisymetrii migrativních agregačních funkcí.
