    Summary: In a bipartite graph there are two widely encountered monotone mappings from subsets of one side of the graph to subsets of the other side: one corresponds to the quantifier ``there exists a neighbor in the subset'' and the other to the quantifier ``all neighbors are in the subset''. These mappings generate a partially ordered semigroup which we characterize in terms of ``run-unimodal'' words.
