Couceiro, Miguel; Meletiou, Gerasimos C. On a special class of median algebras. (English) Zbl 1399.06036 Miskolc Math. Notes 18, No. 1, 167-171 (2017). Summary: In this short note we consider a class of median algebras, called \((1,2:3)\)-semilattices, that is pertaining to cluster analysis. Such median algebras arise from a natural generalization of conservativeness, and their description is given in terms of forbidden substructures.
