Abstract:A poset P=(X,precedes or equal to) is m-partite if X has a partition X=X1union or logical sumcdots, three dots, centeredunion or logical sumXm such that (1) each Xi forms an antichain in P, and (2) xprecedesy implies xset membership, variantXi and yset membership, variantXj where i<j. In this article we derive a tight asymptotic upper bound on the order dimension of m-partite posets in terms of m and their bipartite sub-posets in a constructive and elementary way.
Keywords:Linear order  Multipartite poset  Order dimension
