Kulcsárová, Ol’ga Second note on the theorem of Aleksandrov. (English) Zbl 0990.28014 Tatra Mt. Math. Publ. 19, No. 2, 257-261 (2000). The paper deals with the classical assertion that a subadditive regular set function \(\mu \) is upper continuous in \(\emptyset \). The paper contains two strenghtenings: 1. Instead of sets, fuzzy sets are considered. 2. Instead of a real function \(\mu \), a so-called small system is used [see, e.g., B. Riečan and T. Neubrunn, “Integral, measure, and ordering” (1997; Zbl 0916.28001)].
