ResearchPublished 1970
Every partial order is the intersection of a family of linear orders. The dimension of a partial order is the size of the smallest such family. A new characterization for partial orders of dimension two is obtained by using an old characterization of Dushnik and Miller and a theorem of Gilmore and Hoffman on comparability graphs. 5 pp. Ref.
