Concepts in triadic contexts. (Konzepte in den triadischen Kontexten.) (German) Zbl 0955.06002
Summary: R. Wille defined triadic contexts. In this paper, an “alternative” theory of concepts in triadic contexts is developed so that the appropriate triples of sets are defined by means of appropriate nonempty sets using inner tools of the theory.
06A15 Galois correspondences, closure operators (in relation to ordered sets)
